[Request]: Add graphical information (e.g. a warning icon) when shortcuts point to a non-existent file

Tell us the problem or your need

During disk cleanup, I completely removed Doom and No Man's Sky, but these programs are still shown as available in Bottles. I can even click Play, but the launch fails without displaying any error message.

Describe the solution you'd like

I think there are several possible improvements to this situation:

• Add a warning icon next to a program when its executable file is missing
• Display a clear error message when Bottles fails to launch an application almost immediately
• Remove or hide entries that point to missing executable files

Other solutions?
