If 2 people works on same file, there is something wrong in your firm processes. There is no currently plan to implement it.
If more users will want this functionality, we can start discussion about way how to realize it - setting file atribute, use way like word - create another file what will do lock function. But I don't want to use way to keep file open whole time. -- <http://forum.pspad.com/read.php?2,58435,58441> PSPad freeware editor http://www.pspad.com
