repo directory explorer

There's just too much!!! So we heard users asking for a way to hide some files and folders from the analytics, but in a neverending quest to reduce complexity in the system, we hoped to avoid a whole separate section for unhiding things.

Here's a crumby concept to introduce more logical directory exploration that makes sense to users. What's more, with a bit of styling, we've got an inactive state, where the file/folder is excluded from analysis, but not forgotten ❤️.
