Praying for the day contacts and calendar events will be synced through Proton’s bridge. It could be a drop replacement of google services for a lot of people.
I would love to use the KApps for Calendar / Contacts / Mail for a better integration into KDE. But at this point Thunderbird is just so far ahead, I’m not sure KDE will be able to close the gap to make those apps a viable alternative
Some level of unification would be good. They are simply too different. I’d be more than glad to offer design help for free. The email icon looks too much like ProtonMail’s. That is not OK.
This email icon is a symmetrical blue/purple multicolor gradient with a shaded top. ProtonMail is an asymmetrical design in one color with varying levels of brightness and a blank top. The two look pretty distinct to me. Even without the different colors, the change in symmetry is quite obvious.
I do agree these don’t have unity in their design though as a set, they look pretty generic.
I don’t have a proton mail icon on my desktop though. I don’t think that really matters. A consistency with the UI would be nice though. You could make an icon theme.
