Question

This should be a no brainer.

When clicking on any plug-in present on a channel, the plugin will open but the plugin icon on the channel insert section is not highlighted. Problem is when having the same plug in on different neighboring channels, I get confused countless times and have to double check whether I opened the right plugin on the right channel before making any adjustment. Please fix this

Answer 1

Look at the top left corner of the plugin GUI. It tells you clearly which channel the plugin is instantiated on. No fix required.

Answer 2

I don't think its a fix, but rather an enhancement. Yes you can just check on what channel you are or click on the channel if needed, but it would be a great visual indication less confusion. And it shouldn't even be a lot of work to do I think.
