attachments categorized as notes

[dcohen]

if you add attachments to an item, the column notes (in the item view middle column) counts them as notes; should we make that column "notes/attachments"? that's a little big, but we need to do something about this just to keep things straight

(In [530]) Fixes #206, notes/attachment count incorrect after deletion

The notes/attachment count wasn't going down on an attachment deletion because it's not actually a notes/attachment count at all--it's a notes count, and new attachments were incorrectly incrementing it.

This technically either fixes or invalidates #202 ("attachments categorized as notes"), depending on how you look at it, but I'll change that to reflect the desired goal of having a combined notes/attachments count.

(In [532]) Closes #202, attachments categorized as notes

"Notes" column changed to "#" and combined with the attachment count. "#" isn't exactly immediately self-explanatory, but "Notes/attachments" would be way too long, and once you realize what it's for (i.e. the first time you create a child item), you really don't want the column taking up any more room than that... If people have a better suggestion, do share.
