FR: Panel Intellihide with border options

[Draculah]

I like the option to hide the taskbar for a focused window. No. I like all the options! Though, because the taskbar is not fixed (when inttelihide is on), I find it's often hard to distinguish the taskbar from the application (for dark modes) or whatever darkness may be behind. Therefore I suggest adding an option to either have

• nothing,
• a thin border or
• a shadow

around the taskbar, so that it doesn't depend on one single (background) color to visualize it. I don't want to push it too hard, but being able to modify the/some shadow and border size values would be nice too (or choose from a prefixed set of them) :D

I'd guess the same problem would apply for a white taskbar over white applications/backgrounds, so I think it would be beneficial to everyone, however I didn't test it white-on-white. This hinting color could be those of the icons (white in the first screenshot), or the third color that indicates which apps are open (the purple color in the second) so that it wouldn't conflict with a theme.

I honestly have no clue of whether it would look good - I hope so - but maybe there could be an alternative solution to this that I haven't thought about: "inner shadows" aka gradients?

Use cases

Here I made the taskbar "stuck" using the "show taskbar" shortcut, so it would be visible for the screenshots.

Zorin Dark Gray on shell

To show the need: take a look at the issues page for example: On the right screen, it's hard to find the task bar. Usually, it's okay, because one might press "ctrl i" (default shortcut) which pops up the taskbar, catching your eyes. However, I've configured the taskbar to only hide when focused, so I can always tell the time on either one of the two displays. Looking at the one that isn't hidden by a focused window, it gets harder.

Dracula gtk on shell

Also, as I find the dark themes only okay-ish, I decided to switch to the dracula gtk theme. Using that theme for shell (taskbar included) will make the taskbar even harder to see on the very consistent dracula theming for applications like Visual Studio Code. Of course, that's just my problem - I could switch back to the slightly clearer zorin-gray-dark theme for the shell - but the shadowing (or whatever hints) might solve that as well. Again, I'd hope :p

Also, an informal big thanks to the developers; the transition to linux was scary, but gentle thanks to Zorin OS. No regret.
