Hi,
I would like to configure app to see only relative paths in Path column, especially when I search only in one path. Or separate columns for full and relative paths.
When searching in long path my screen is cluttered with unimportant info.

Hi, yes, exactly like this.
It could be an option for "Path" column, or there could be another separate column "Relative path" which can be added/removed in settings as other columns can already.
I understand it complicates a bit when searching in multiple paths, I see two solutions:
1) the feature not availabe when searching in multiple paths (this would be better for approach with option for current Path column), or
2) the feature availabe for all search paths, nevermind that user might not be sure in which of search paths the result is found - this might be better for approach with separate column "Relative Path" - user can always use normal Path column instead.

I personally usually search in one path .
This should be very easy to implement especially with approach of separate column "Relative Path" - just make "string replace" on what is in Path column .
