One-click clear of status/category filters to "all" or "all open".

[timbl]

Buttons to select view all (instead of having to manually select) in the column filter for status (etc).

It is a pain to have to reselect all of the parts of a pop-up selector, especially when the popup is inside a scroller.

(In chrome, if you select one, and then do Command/A, then it selects all of them bit does not have an actual effect on the display. But maybe that is from not catching that form of change in an event? Or a chrome bug?)
