As in, select all the samples in a particular column (also, do the same for the row as well).
It would be nice to be able to click the top sample, then shift-click the bottom one, and all in between get selected.
Alternatively, it would be nice to allow click-drag marquee selection, without Shift, starting over a zone when Lock Zones is enabled.
Currently the click-drag marquee selection works only when starting over an empty area in mapping editor.
Yes. In this particular case there is no empty area.
