As I do more and more in RMXP, I find myself creating very complex events, with bunches of conditional branching. I also end up with maps with all sorts of events on them, and re-using that map in a further segment of the game starts to become more problematic. Personally, I'd love to be able to call and delete dynamic events, based on the current situation. I know the common event sort of handles this, but to me doesn't seem dynamic enough. Script access to creating/deleting events would be tremendously helpful, IMO...
One this I really dislike about the event manager is the tedium to put in a event, and then to edit the event. If I double click a blank event line, let me enter one. If I double click a line that already has an event, let me edit it. The whole right click bugs me. Then doing a move route sometimes, is click, enter a value, click, enter a value, over and over again. I'd actually prefer just to type in the event commands... If only it was possible.
