Suggestion: Convert columns A-K into a table w/ filters so we can filter by number of sockets, or by item base types. I'm currently using the sheet to see which socketed items in my stash I can use up in pursuit of the chronicle, and noticed that would be helpful to have.
edit: attempted doing this the easy way and realized it will mess up the "remaining runes" counting, so it's a little more involved than I thought
You're right and I ran into that at one point. Filters will offset rows/columns for the remaining runes data in the background and probably mess up the count. I could possibly solve that problem by putting the counting on a separate sheet. Alternatively, you can try "sorting" by the "number of sockets" or "item base" columns as opposed to "filtering." That should work without breaking the count.
Glad to see you're making use of it!
