I’ve quickly put out v0.2.2-beta.3 which hems up the prefix/suffix problems.
Most importantly, I found that I had stopped sanitizing the rest of the path. Doh. That simply fixes a lot that seemed like a step backward (it was).
Then, most of the “open directory” buttons around the app should work now (tell me where/platform).
Depending on the feedback from this, I’m about ready to release it.
