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

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

@narcell I wasn't aware the plugin window was black in dark mode. do you mean the console window background?

There is very little chance that dark mode will not be disabled in the 0.52 version. Getting it to look consistent is just too much trouble. You could try making a pull request for Pd to do that, though.

@seb-harmonik.ar Here is the plugin window that you made in dark mode:

And here is a "classic" Pd window in dark mode:

It looks like you solved the problem with the dark mod in your own plugin.
So your plugin is working correctly so there is something what is fixing the whole dark mode problem. I guess. What do you think?

@narcell I have no idea.
In addition, here on MacOs 10.14.6 mojave it doesn't look like that, even in dark mode the window is still light..

New release https://github.com/sebshader/pdnext/releases/tag/0.52-1

includes helpbrowser without limit to the number of panes (though there is sometimes flickering when navigating to new panes)

a tk event <<WindowClosing>> is now generated when windows are closed (probably not very useful to most)

also included are new colors:
atom_box_focus_outline - outline of gatoms with keyboard focus (defaults to black)
text_window_hl_text - color of highlighted text in [text] window
helpbrowser_hl_text - color of highlighted text in the help browser

https://github.com/sebshader/pdnext/releases/tag/0.52-2

added pdwindow_hl_text, color the text is highlighted in the pd console window

compiled a universal binary for mac intel x86_64 and arm64 (apple silicon m1 chips)

Found, and installed painlessly, this is really nice stuff here. !!

v. 0.53-1 has actually been ready for a bit, with a new graph_open color type (for opened GOP subpatches in the parent, currently a grey box)
unfortunately my macbook died and my new laptop isn't powerful enough to run VMs well I think (not macos anyway) and I had a lot of trouble cross-compiling wish.
So, windows and mac builds may take awhile.. unless someone else wants to build.. maybe I'll try to get some CI thing to make a release..
https://github.com/sebshader/pdnext/releases/tag/0.53-1

releases page has a windows build for 0.53-1 now

got a new release https://github.com/sebshader/pdnext/releases/tag/0.54-0
testing needed on macos
