Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Marked possible code improvment for future activities: parameters stored in the settings were not trusted. LastDive ID and Sample index are usually calculated at startup. This calculation could be avoided, nevertheless the implementation works => only TODO Removed function without effect: Calling writeblock with legth 0 has no effect
