Some possible UI improvments

[ids1024]

Looking at the GTK interface for Popsicle, it seems pretty simple and intuitive, but it seems like some UI elements could be a little bit clearer. I can think of a few things that could perhaps be improved:

• The "check" button for the checksum is at the bottom right, and in the same style as the next button. At first glance, it's easy to expect this is the button to go to the next step.
• When selecting a USB drive to write to, the capacity of the drive isn't shown. Though it looks like DevicesView does at least show when the drive is too small for the image. Seeing capacity listed can make it clearer that the device is the one the user expects.
• When flashing, a transfer rate is shown, with a progress bar. It could be useful also see how many bytes out of what total has been transfer, and perhaps an ETA. This could made it a bit more cluttered, but these a fairly common things to display in such a context.

For comparison on a couple of these points, compare Ubuntu's "Startup Disk Creator" and Fedora's "Fedora Media Writer" (both installable from Pop!_Shop):
