Clearer tabs, maybe?

[NickEJ]

I'm wondering whether it might be possible, either through a setting or some interface enhancement, to make the tabs in Affinity Photo a little clearer. I'm visually impaired and the super-low-contrast difference between tabs denoting open images is really, really hard to see. This means it's kind of a pain to switch between them. Of necessity, I've gotten a bit fluent on the hotkeys, but it would be sweet if there were a setting to make the tabs, say, different colors, if only at the top. 

I realize this is probably a pretty niche request, so no big. I love the entire line and have recommended it to many students who are just fed up with the Adobe Tax.

There are several other threads requesting this.
