Disable Undo For Search And replace

[whiskyjb]

I'm preparing huge datafiles (150MB, 1.5 million rows). I often search expressions and replace them with others. If I cann't do it with unix/perl/awk/sed, I'm using Textpad but getting problems with memory because all changes are tracked in the undo buffer.

For such search/replace actions, there should be the possibility to disable undo functionality.

Uncheck Configure -> Enable Undo.
