IDE, remove multiple items at once?

I got a little carried away when I didn’t know what I was doing and ended up adding a ton of items from the smartthings public repo to my repo… I realized I don’t need them in my repo and now I want to get rid of them to tidy it up…

Is there a way to get rid of multiple smartapps/device types at once? It’s cumbersome to delete them one at a time.

Worst case, is there a way to wipe my personal repo and start from scratch?
