Agree with @mmdj2 about the size. Otherwise, really nice!
Maybe you could mention the AltGr issue with 2.1.28 somewhere. As I understood it, you have to wait for a Qt fix for that? Because it makes 2.1.28, as cool as it is, almost unusable for people with keyboard layouts that rely heavily on AltGr combos. As a German user, I cannot for example type any of these characters on 2.1.28: @{}[]~²³|
Edit: Tried the alternate version, and it works there!
Edit 2: The “normal” version allows for CTRL+mousewheel zooming in the Add Card webview, the alternate version doesn’t. Is that simply due to the older Qt version on the alternate? Because when I discovered that 2.1.28 supports this feature, I was really pleased as it adds a lot of convenience when switching between different screen sizes.
