Grouping, Auto-Scroll , Selecting Multiple Elements
You may also want to consider following features for next updates (of course if you find it useful):
1. Grouping of Front Elements- this will allow scale Front Elements more easily
2. Auto-Scroll while drawing selection box- while selecting the flow chart larger than visible screen, it is better to auto-scroll the screen to select it entirely.
3. Multiple Object Selection using special key (like shift or control) + click
