XTREE refinement: XTR'SELECTAREA bit XTRSEL_EDIT_KEEP now works with the other XTRSEL_SEL_xxx (selection bar) styles, preserving the entire selection bar display during editing. For example,

XTR'SELECTAREA = XTRSEL_AREA_ANY or XTRSEL_STY_ALL or XTRSEL_EDIT_KEEP

will leave selection bar highlighting the entire row during editing. Note that this is a visual change from the prior interpretation, in which XTRSEL_EDIT_KEEP acted like XTRSEL_STY_CELL1 during editing, highlighting just the first cell on the row. To get the old behavior, 'OR' the two together—i.e. XTRSEL_EDIT_KEEP or XTRSEL_STY_CELL1.

Also note that in the case of gradient selection style, the style is temporarily changed to the normal selection bar during editing and then changed back to the gradient style during selection.
