I think my original reason for doing this was to prevent the button
from being operational until after the spinner initialization has
completed, so you don't get any weird half-functional spinner buttons.
However, in practice I'm finding that I constantly forget about this
and it adds tedium to creating spinner buttons.
Will review if any actual problems come up.
1. When the list is long, scrolling back up to hit to search
button is annoying.
2. If you select too many, there's no way to know if you're
going to wind up constructing a search with 0 results thus
wasting your time.
I've been thinking about this for a while but couldn't think of
the perfect way to implement it. I still haven't, so instead I'm
just starting with something and we'll see how to improve later.
At any rate, I can update the rest of the system to expect Albums
coming out of search so that if I ever have a better algorithm
everything else will already be ready for it.
For this first experiment, just any photos that are part of an album
will send that album out as a result. It doesn't even respect the
limit parameter, it's really just to see how it feels to use.
With a name like add_searchtag you'd think it'd be past the point
of reading box input, and deeper into the abstraction zone. But nope,
it wasn't. I'll try to take this a few steps further from here too.
I think at one point I was using full qualnames on the tag objects
in the mmf uls. But now they just show their base name, so this
code is useless. And I don't think I'll reinstate it because tags
have multiple parents now and I don't want to implement all the
lineage checking in the client js. We'll just let the server handle
the slightly less efficient query.
On the main tag listing, for child tags, you only get an unlink
button on hover. So if you want to delete a child tag you'd have to
unlink, then refresh, then delete. Now you can just go to its page
and delete it there.
