Added two more buttons to Scheduler, which allow moving selection directly up to top with "def _firstPos(self)" or directly down to last Position with "def _lastPos(self)".
I think these changes work so far and do not interfere with the original code.
Reworked with removing whitespaces in 90, 102, 125, 135 and changing Labels to "First" and "Last"
