I added your proposals and merged.

Excellent! We can deal with that later on.

Ack!

In my tests this matched (with the new "amd64" architecture):

    tails-amd64-x.y.

And I was still missing the minor version.

I proposed 22 chars in my previous email but apparently the minimum
chars to fit "tails-amd64-3.12.3.iso" is 17, probably due to the
non-monospace fonts.

So I really want to have a minimum of 17 but then I don't care much
about the exact value.

Also, right now if I make the window wider, the file chooser doesn't get
wider. That would be another way of preventing having the filename
partially hidden. Feel free to do this if that's easy :)

Ok.

Fair enough :)

Ack!

Switching between "Install" and "Upgrade" is still broken for me :(

If it's what you meant to fix with 885be99, maybe there was a
misunderstanding. The problem is that when plug two USB stick (one with
Tails and one without Tails) and switching between the two in as target
USB stick, then the Install button doesn't change to Upgrade.

Ok :)

So we only have two small issues remaining:

2. The chars of the file chooser
6. The switching between Install and Upgrade.

I can do the patch for #2 but not for #6 so unfortunately, I have to
reassign this to you again :(
