I've been encountering situations where I need to select a number of titles, and it's beyond what I'm able to do with filters and searches.
For example, tonight I needed to locate all titles with an IMDb URL that were added in the past 3 days, but did not have poster/cover art, did not have anything already in the "description" field, and weren't TV shows. So I used CTRL+select for this purpose, but frankly I get nervous when I start doing that with 100+ titles, since I'm always afraid I'll accidentally click somewhere without the CTRL key pressed, and erase all my selections.
What I was thinking was that a checkbox (or some other method of temporarily "marking" the title entries) would allow me to easily go through the database (whether it was filtered or unfiltered) and select whatever titles which happened to match my particular needs, and then be able to perform any action on those titles as if they were selected in the normal manner.
Such a feature would ideally also have an "inverse select" and of course a "clear all selections" option, as well.
Thank you again!
