In dialog mode, the columns combobox now works properly as a search bar. When you type something, the cursor stays at the end instead of jumping to the beginning.
I wonder if there is a way to 'Sort by Selected'. I'm looking for this.
For use after running the Dopus 'Select By Pattern' feature, and so everything that got selected by the pattern is moved to the top, like a group. Still in alphabetical order, or by order of the current column filter, but the idea is to divide what is selected from what is not selected, for easy review of what the 'Select By Pattern' selected.
To answer my own question, so it's not followed up on in this thread:
With help from PassThePeas I learned that I can hide things based on their selection.
Hide selected:
Select HIDESEL NOPATTERN
Hide unselected:
Select HIDEUNSEL NOPATTERN
Show whatever has been hidden by these commands (doesn't affect the H attribute)
Select NOPATTERN SHOWHIDDEN
I made a three-button button for this. And can add these commands to whatever I want, to do multiple steps like select by pattern then hide the unselected. Not as good as a selected to top group because you can't compare the selected with the unselected, but close enough.
