A selected item (marker, track…) is indicated with a dotted line as "Current" in the display if and only if the selection is made by the corresponding Layer tool.
But selections for editing may be made in ways other than by using the Layer tool (e.g. right-click with any tool, a very worthwhile capability). However, then there may be an uncertainty, or no indication at all, of which item is being edited.
Suggestion: Always use the dotted line indication of selection ("Current"), whenever an item is selected for any editing, even if the item is not selected by the corresponding Layer tool (e.g., by right-click or by highlighting).
An Example: With one item indicated as "Current" (with the dotted line in the display), a different item may be selected (highlighted) and edited in an Edit Layer window, leaving the "Current" status as it was, thus editing is not done on the “Current” item. Why not have the "Current" status changed to the highlighted item, eliminating the ambiguity?
Another Example: A track may be split at a point selected by any tool (right-click). But the two split pieces are not distinguished, either as to which track is selected for a split or where the split was made, unless the Track tool is used. Why not distinguish the track and pieces no matter which tool was used to select the point of the split?
