- Fixed and polished how we scroll/drag or zoom data in timelines using mouse. It should be much easier now. - Added scroll bar while working with zoomed data. It's clear that we have it zoomed and it's faster to scroll that kind of data now. - Fixed how timeline's context menu works with timelines selection. - it's possible to copy log lines to system clipboard now, - bunch of other fixes and tweaks here and there (like GrabHand" mouse cursor while dragging timelines, etc.) [CL 2383375 by sebastian kowalczyk in Main branch]
