Bug 300041

I want to view images that have any of several tags.  It is way too hard to do this--something that should be basic.

1.  I try the Tags left-hand pane: I can only select one at a time.
2.  I try selecting the root "My Tags" in the Tags pane, planning to use the "Caption/Tags" right-hand filter pane to select more than one: but the filter pane becomes grayed out.
3.  I try to view the "My Albums" root, but that doesn't show anything.
4.  I try to view the root path underneath "My Albums", but it also doesn't show anything.
5.  Nothing helpful under "Search."
6.  Finally I try an "Advanced Search" with "All of the following conditions", and select multiple tags: This appears to work, except it makes no sense: by selecting "All of the following conditions," it should only show images that each have ALL of the tags I choose--yet it returns images that have only one of the selected tags.
6a.  There is no way to "select all" tags or "select none" tags in the Advanced Search--I have to do it one at a time, click by click.  This is painful.

Bottom line: this is way too hard.  The whole point of tags, rather than folders, is that images aren't limited to one folder or tag.  It should be easy to see images from multiple tags.  It should be as easy as multi-selecting several tags in either the left or right panes.  This shouldn't require an "Advanced Search."

Reproducible: Always
