When you base everything on top/left, it seems that check outline always seems to go down to 0,0 as part of the sequence. It also seems to always track the X0 line even if the only image loaded is set further into the bed. Is there any way to get the check outline to only preview the boundary of the loaded images?
Also is there any setting that would speed it up? It doesn’t seem to obey the default speed setting in LW.
