Hi,
When selecting a line via triple-click, then extending the selection by shift-clicking on another line, the behavior changed.
TM1 (and other OS X apps like TextEdit) would select everything in between plus the ENTIRE clicked line.
TM2 only selects up to the clicked point.
Same for double-click selection (select word): TM1 and others select the entire word when shift-clicking, TM2 only up to the clicked point.
Should probably be changed to behave like TM1 did to be in line with expected behavior on OS X.
