v3.1.1

Fixes

• Thousands of files added or deleted at once across many folders, like an unpacked archive or a big checkout, enter or leave the index within seconds, where new folders used to wait up to an hour for the next full reindex
• Everything picks up thousands of files added or deleted at once within seconds, instead of walking the whole disk again for each of them
• A big git checkout no longer makes Cling walk the same folders over and over
• The search window does less work on each redraw when you have many quick and folder filters
