Editor improvements

1. I would like to be able to mark multiple symbols by drag and drop, now the only way is Ctrl+Click 2. I use Ctrl+Drag to copy symbols in ProcessBook as I find it quicker and more precise when adding new objects to the display. 3. Quick edit the tag/attribute on a value symbol: Change the tag/attribute on a value instead of having to add a new value from right hand menu 4. Sizing: It would have been great having a sizing toolbar to set an absolute size, now it’s difficult to add two symbols with the same size 5. Text alignment: I would love to have the alignment (left, right, center) easier available like most editors have and not in a sub-menu. 6. Center alignment is not kept on data-update – The symbol only resized to the left 7. Possibility to change background color.
