I've already made some changes to the program. You can now select tiles from the level window with the "B" button and can select Events and paste events without going to the event window by using the Ctrl + E and Shift + E combos. I also plan to add Event names... only for the event window and not the Level window. This should make people a bit happier. I'm also making an Undo function.

[Edit]

Ok... all the above was implemented. The new version should be up shortly. Check back here and we'll tell you when the new version is out. A lot of bugfixes and special features were added. =)
