Firstly, all of my Listers are identical and have the same Column Names and Positions: Name, Size, Type, Modified, and Created
What I need to do:
❶ Create a toolbar button or a hotkey which makes the "SHA-1 Checksum" column appear and also always be positioned as the 2nd column, after the "Name" column header (which is always the 1st column in all of my Listers).
❷ Make the "SHA-1 Checksum" column ONLY ACTIVE in the folder it was activated in initially. If I go to another folder, I want the "SHA-1 Checksum" column to be deactivated automatically. Sometimes I will go to a folder which contains a lot of very large files and, forgetting that the "SHA-1 Checksum" column is still active, the Lister will start calculating the SHA-1 Hashes of those files. I then have to close the Lister to deactivate the "SHA-1 Checksum" column, then open a new Lister and navigate back to wherever I was trying to go to in the first place.
What I am doing now:
I am currently bringing up the "SHA-1 Checksum" column manually by right-clicking on a Column Header and drilling down to the proper entry, like so:
This is kind of tedious. I have done a lot of searching for a solution to my problem, but I think I'm just a little too dense to figure this out, so...
TL;DR: Create toolbar button or a hotkey to activate "SHA-1 Checksum" column in the current folder only, then automatically deactivate the column if I leave that folder.
As always, thank you for your help
