Currently, when I edit things near/crossing map borders, I
1) edit level A
2) click on level B on the minimap
3) scroll back to the border of level B (minimap is not that precise :/ )
4) continue editing

Instead it may be better to perhaps switch to the next level by scrolling towards the level (against the map  border) and initiate the level switch by pressing shift.
So you scroll towards the border at X=00 Y=13 on level A, press shift,   then you find yourself at X=99 Y=13  on level B. (we may want to reset the scrolling dot/current scrolling process as soon as the the level border is crossed.)
