show open instances

Hi!

First congrats, I enjoy where appfinder is going: the vim keybinds, allowing to hide window decorations and hiding it when focus is lost. All very good stuff. It's getting to be a cool built-in xfce launcher.

With this new behavior the app feel much more like macos spotlight or even rofi.

You can close this issue at any time as it's more as an idea and maybe it doesn't fit with your vision but it would be appreciated for some users if appfinder had an option to show the open instances of applications at the top. The use case is the following one.

• command + space to launch appfinder centered on the screen without decorations easily
• currently we are on workspace 1
• on workspace 4 firefox is open
• I search in appfinder from workspace 1 for fire, and the open instance shows before the new instance
• by selecting the "instance one" the open firefox on workspace 4 is focused

This help to achieve a very focused workflow, not so dependent on knowing a lot of shortcuts, or reaching for the mouse. When you have a lot of stuff open alt + tab is less efficient.
