Show the current workbench in the status bar

From @argenos on Discord: is there any way that we can get some info in the status bar about which note is my current workbench note? I'm a bit worried that I'll get distracted and accidentally clear one workbench note that I didn't intend to use as a temporary one

I think another (easier) option is to have a toggle to disable the clear command? Or restrict it to Workbench.md? or something like this?
