It would be nice if one could have a project variable that would be used as a regexp for the filename of files to omit from any search.
I guess what I could do is change the folder references pattern, as the files are not only not supposed to be searched, but not to be added to the project at all. Doesn't keep all problem files from slipping in, though.
I don't know how easy it would be for Allan to incorporate this into the current search system, and given that he is planning to rewrite the entire project system anyway, I would guess it might not be too high up on the priority list ATM.
If he could just implement a "press esc to halt find" feature, or anything, just to save me from having to kill tm, I'd be more than glad while I wait for the project rewrite.
