Ok I understand that. Too many good ideas but not enough time. And too many things that waste your time so you can't put all your ideas in place with the limited time you have.
As for tooltips and various other stuffs, there are some tricks how to increase the speed of WE, for example, Unchecking the "Window - Brush List" would decrease all the tooltips loading time thing greatly, like 4 times
As for the maps, I still remember how someone told me
"I'll make the ground and running ways, and you make the towers, the creeps and that they run on the running way Ok? I will add you to credits!"
People who are new to WE usually don't know how long it takes to finnish a map, thats why there are many "noob" maps.
I mean, the only way I found it makes you do work on your map is to limit the time you work on it daily, so althrough you would work slower, you would do more.
Actually in the worldedit I heard that when you are renaming a unit or tooltip or something you should go to window and close un-needed things at the moment. That makes it go much faster. Well it did for me.
You are not alone. Alot of our members have dozens of unfinished maps. Hint, concentrate and focus on finishing one and releasing it - then see what happens. Don't forget to submit any map that you do finish to our maps section http://world-editor-tutorials.thehelper.net/maps.php
Ghan has said he has fixed this. Monovertex please confirm this fix. This was only a problem with people that had signatures in the upper levels like not the special members but the respected members.
