2.6

Problem you are trying to solve

chrlauncher indefinitely retains old Chromium versions in the \bin folder, causing a lot of disk space to be used up unnecessarily over time.

Suggested solution

Add a "Keep last n version" parameter (default to 1?) in the UI and delete all older versions automatically upon successful updating.
This is easy enough to script externally, but would be a great additional native feature!
