is this spinner the right size?  it looks too big in the video

[dpapad, 2016/09/20 00:52:36]

See http://imgur.com/a/6WO3s. It is 28x28, so sizing seems OK, but it is a bit
misaligned (closer to the top of the row).

wat?  you're disabling the /cancel/ button?  why not disable the ... clearing
button?

[dpapad, 2016/09/20 00:52:36]

The clearing button is already being disabled, using the same boolean.
