ability to select by [field] and perform [action] on all returned entries
I'd like to be able to select a set of entries which correspond to some searchable field (e.g. tag, date range) and perform one of something in an allowed set of actions on the returned set (e.g. change privacy, add tag, delete entry).
Currently, you can edit privacy on entries within a given date range. I was initially going to make a request to add the feature of editing privacy on entries with a specific tag, but there is a desirable general possible feature.
There is a select number of fields for which it is reasonable for a user to grab a selection set of entries. Date range and tag are the two that come to mind for me, but possibly others might want userpic, mood, or some other field. In theory there could also be fulltext search on subject or body, but that could get a lot more complex, and I'm trying to think through the implementation in any reasonable way.
There is also a select number of actions for which it is reasonable that a user might want to act en masse on the returned set. Edit privacy, delete entry, add tag, change userpic... I can't think of any others off the top of my head, but there probably are some.
My use case is that I would like to change the privacy of all entries with a specific tag, but I can definitely see more expansive use cases.
This seems like a good candidate for a paid feature, because it could get fairly processor intensive depending on its popularity.
Should be implemented as-is.
Should be implemented with changes. (please comment)
Shouldn't be implemented.
