FlashSpace

As FlashSpace is not a window manager (only a space manager), application windows can overlap simple-bar.

This can only be avoided if you have a Mac with a notch as it prevent windows to be placed under. If you are using a window manager next to FlashSpace, it may be possible to set a gap in your settings that would prevent overlapping.

If simple-bar is partially covered, you can enable its "Compact mode" in the settings module. You can also set a custom --bar-height value in "Custom styles" tabs in settings.

FlashSpace integration settings

In order to make simple-bar refresh on workspace change, you'll need to "Enable Integrations" in FlashSpace settings > "Integrations" and add this command in the "Scripts To Run" rows:

shell
osascript -e 'tell application id "tracesOf.Uebersicht" to refresh widget id "simple-bar-index-jsx"'

That way, simple-bar will be refresh "On App Change", "On Workspace Change" and "On Profile Change".
