I installed 0.43 vanilla from the source to check out the GUI functionalities. but I cannot get those functionalities I see on these screenshots.

I guess i should enable some GUI plugins before I could use them, but i could not figure out how..

Any help on which file to modify etc. is greatly appreciated..

thanks

as i figured it out, i just needed to find the corresponding tcl file for the plugin. and add its path to the pd.
