Basically this is simple: you can bind "add ___" with keyboard to improve your map making.
For instance, you can make "add wall" by simple pressing L(cuz w is used duh), "add trigger" by simply pressing t etc.
If possible, it should be customizable by user to using those shortcuts.
This post my be simple, and not even my normal style, but hopefully people can share with it and I may release a whole list of suggestion of short cut keys of all blocks.
