So far, I did not think that this might be needed (as you can see where the mouse pointer points to), but it might indeed improve usability in the level editor (and might feel better for those used to the GDash level editor).In the editor it would be cool if the actual position is shown somehow. Maybe a blinking tile or a border around the tile when moving the cursor/mouse (GDash uses this method).
There is no selection tool in the R'n'D level editor for BD levels, as R'n'D always converts native BD levels to "flat" caves, that is, there are no "BD level objects" anymore like in the GDash editor (where you can select and move whole objects made from several game elements like the two lines of walls in the first level of the classic first BD level set). That's why a selection tool does not make sense in R'n'D. As you have mentioned, there's still the "pick drawing element" tool available, to select single game elements from the playfield, which you can either activate by pressing the corresponding tool button, by pressing the "," (comma) key, or by holding the Ctrl button while clicking with the mouse pointer at the game element to be selected on the playfield. (However, using this "pick drawing element" tool as the default tool in the level editor seems to not make much sense, as it switches over to the normal drawing mode after used once anyway.)And somehow it is unusual that there is no select tool (as far as I can tell it's similar to the pick up tool in RnD) as default selection tool. The way it it now it's very likely that objects are drawn by accident when clicking somewhere. I know that pressing CTRL + Pickup tool represents more or less the same. The selection tool should be the standard tool by default in my opinion like in GDash to prevent any actions by accident...
