It would be great to bring the Proton Calendar widget's appearance into this decade – it currently feels a bit outdated, with only black or white background options. I’d love to see more flexibility and visual polish. It would be awesome if:

There were transparent or semi-transparent background options for a cleaner, more modern look.

Users could remove the calendar color sidebar that appears next to each event.

We could customize the text color, or let events inherit text color based on the calendar they belong to (e.g. Calendar A = blue, Calendar B = green).

I’d also really love to see two separate widget types:

A calendar view widget that shows 1 week, 2 weeks, or a full month in a date grid format – with a simple one-line header showing the current month.

An agenda view widget with upcoming events – also with a one-line header showing today’s weekday and date.

For reference, something like the Event Flow widget is a great and stylish example:

Right now, the current widget doesn’t really blend in on the home screen – it just sits there as a big black or white block. A more flexible design would make it far more usable and attractive.

Thanks for considering – I think many users would love the added flexibility!

Not my original idea, I found the suggestion in an old deleted reddit post on r/ProtonMail, but it was oddly devoid of any response or acknowledgement. The user has since been deleted, or I would fully credit them.

Make a 1x1 widget that displays the Proton Calendar icon with the number of the current day of the month, thus it bypasses the OS limitations mentioned by Proton in a similar request here on UserVoice.

Tapping on the widget would then open Proton Calendar as the regular icon does. This widget can then be used as a normal app icon.

The existing Proton Calendar widget is honestly very bad looking and has no customization options. It would be nice to have different formats, viewing features and the ability to choose the color/transparency.

Idea: Develop a versatile Android widget for ProtonMail that offers multiple size options (1x1 to 4x4). The widget should display recent email previews, unread message count, and include buttons for quick inbox access and email composition. Users should be able to customise the widget's appearance, such as colour scheme and information density, to suit their preferences and home screen layout.

Proton Calendar already has an Android widget that shows line-separated, upcoming calendar events.
