Hi!
I have this custom column '#last_viewed' (Date type), which gets updated by JS+ plugin upon opening any titles in the library.
Now I'm thinking it might be interesting to have something like a "Long text, like comments" column that could store every #last_viewed timestamp, perhaps separated by line breaks or spaces.
Then I see two issues: 1 - Long text columns can't do template language, and 2 - If this actually could be feasible using a "Column built from other columns", which can receive template language input, I have no idea how to reference custom columns as *I* can't do template language.
