I posted on the list, but thought I'd post here too..
Here's a Pd mod that I've been using. You can use color themes like in Pd-extended. There are also different inlets/outlets and cords for audio or messages.

I also put initbang and closebang back in
Unfortunately only tested/bundled on OS X
https://github.com/sebshader/pdnext/releases

I also updated tclpd which works with this bundle now
https://github.com/sebshader/tclpd/releases/tag/v0.4

here's an example theme
colors-plugin.tcl

@60hz putting these lines in some .tcl file in the pd path (maybe even in the colors-plugin.tcl file..) will do the trick

proc redraw_cords {name, blank, op} {
    foreach wind [wm stackorder .] {
        if {[winfo class $wind] eq "PatchWindow"} {
            set canv ${wind}.c
            foreach record [$canv find withtag cord] {
                set tag [lindex [$canv gettags $record] 0]
                set coords [lreplace [$canv coords $tag] 2 end-2]
                ::pdtk_canvas::pdtk_coords {*}$coords $tag $canv
            }
        }
    }   
}

trace variable ::curve_cords w redraw_cords

@seb-harmonik-ar
Thats working perfectly in color-plugin.tcl! Thanks.

Another question regarding inlet/outlet: now the msg_cord color is corelated to iolet outline color.
In order to make even better themes do you think that it would be possible to have a separated outlet outline color? or be able to have no outline in iolet?

@60hz I've been thinking about that too.. thought it would be cool to have the cables always be the same color as the outline, and also to cut down on "option bloat"

but I might put it in just to have the option.. I probably won't compile/release again until the next major pd version tho.

@60hz ok I lied.. I decided to get it done now..
new release
https://github.com/sebshader/pdnext/releases/tag/0.51-2
it's msg_iolet_border and signal_iolet_border

@seb-harmonik-ar great!
My theme is ready, less confusion between objects and messages boxes for students, and everything is readable

Here is the plugin : colors-plugin.tcl

I would love to use it on linux!!

@jcorrea because each distro packages apps differently I didn't bother making any linux packages. However compiling from the latest master git sources should work fine, and I've successfully built and installed it on arch linux

btw there have been a few more issues I found over the last month on osx with the version of wish I was compiling and packaging (gui slugishness, permissions issues). Everything should be fixed on the 0.51-2 release page now though.

@seb-harmonik.ar Thanks for your kind and fast reply. I will try to compile and let you know how it goes.

updated to 0.51-3 https://github.com/sebshader/pdnext/releases/tag/0.51-3
used updated (fixed) tk with no-scrollbar and disabled-help-menu-items fixes on osx, in addition to the font and permissions fixes from pd 0.51-3 (and the new expr functions)

Hi nice Color Themes! What is the exact procedere to use this seb?! I downloaded a build from your github repo, but when i start PD NExt, the color is like the color in PD vanilla

@tungee the colors are set through tcl variables in a .tcl plugin loaded by pd when it starts. An example file with documentation is in doc/7.stuff/colors-plugin.txt. If you change the extension to .tcl and save it in your pd path you will get an example theme I was using awhile ago. From there you can change the hex values or tcl color names to get the values you want.
or you could try @60hz's .tcl file as a starting point (just download the .tcl file and put in your path)

Maybe I should try to mention this on release pages...

fixed a tk regression/bug with patch window sizes on osx. updated on release page

@seb-harmonik.ar would it be possible to update your mod to pd source 0.51.4 ?
The next ceammc lib will need last pd to have all of the features

@60hz I'm not aware of any new features since 0.51.3 (which ones would ceammc need?), but I went ahead and updated anyways (w/ an improved "font" dialog & fix to "stretch")
https://github.com/sebshader/pdnext/releases/tag/0.51-4

@seb-harmonik.ar
That's great!
All is working nicely with the next ceammc pre-release, the only drawback I see is that all tick boxes doesn't work in ceammc properties:
https://github.com/uliss/pure-data/issues/118#issue-830759712

I think it might be related to tcl/tk 8.6.11...

@60hz do you get that with vanilla too or just w/ next? vanilla distribution is still using 8.6.10 afaik
edit: I downloaded the library, which properties do you mean?

yes, it works well with vanilla in OSX 10.15.4 for me.

I talked about the Right clic -> property on any ceammc ui objects

@60hz I figured it out, seems like you're right. Might be pertinent to mention in the bug report that it only doesn't work with tcl/tk > 8.6.10

@seb-harmonik-ar
I have many little ui bug with the last version of next compiled with tcl/tk 8.6.11
https://github.com/sebshader/pdnext/issues/2

Is there any needs for this pecific tcl version?

@60hz I replied in the bug report, but basically the event loop handling is supposed to be much more stable and improved on modern macos with 8.6.11 from my understanding. For instance, 8.6.10 required patching to get the scrollbars to show up on newer osx (also this is why there are 2 different releases for osx on miller's site I think). The patch was kind of hacked out of 8.6.11 which changed the architecture of its event handling since 8.6.10.

I noticed the bug you mentioned in an earlier release with tk 8.6.10, and the fix was actually merged into main pd vanilla. I cannot reproduce on osx 10.14.6 so unfortunately I'm not sure how to go about fixing it..

as for the ceammc bug, it is an issue with tk 8.6.11 with the ttk "alt" theme and has to be fixed in either ceammc or tk.
However you can still package w/8.6.10, I suppose I can upload a version using it instead if it makes that big of a difference..
