How to not filter sub-directories?

[GrantSP]

If I have a folder with many directories and sub-directories that contain different types of files. If I use the filter to show only, eg *.sql, the sub-directories are hidden as well.

I would like to be able to navigate up and down the 'tree' using the file pane while it shows only the specified filetype.

As it is now I must disable the filter - go to a new folder - re-enable the filter - do whatever actions I want - disable - move - (repeat).
Or use the tree view (Alt + Num*).

Similar to this request is the ability to reverse the selection. ie set the filter to eg. - *.sql and have the display show everything but *.sql files. Or have a button to reverse the selection.

"*.sql /*"

View filter starting with / specify a folder filter. so *.sql for only the sql files and /* to show all folders.

Include this example with description in tooltip for future versions. I think many people do not even know of such functional existence.
