Better indicator styles
I would suggest to improve the bars indicators by splitting the bar into parts. If 2 windows are open, split it in half and leave a gap between the bars. Like this:
You can go as much as 4-5 splits:
It makes it a lot more obvious.
Another suggestion: when hovering any icons in the dockbar you should highlight those bars or whatever style is used for the "active indicator" to, again, be a bit more obvious.
Thank you for this plugin. It is very good!
