Not sure if I understood the idea description correctly, but if this is about pinning meetings and rooms that I was invited to - this would be very important for me, too.

Currently, "My meetings" and "My rooms" only show meetings and rooms that I created. They do not show meetings and rooms which I was invited to (i.e. received a link). If I understood the original poster correctly, that is what they are describing. This would be a critical feature for me.

Supporting arguments:

1. Suppose I am a member of a team and we frequently want to do quick exchanges. That is what meeting rooms are for. For the owner, joining the room is just one click from the main page. For the participants, it requires each time retrieving the link, pasting it to the clipboard, switching to Meet, clicking on "Join via link", pasting from the clipboard, hitting "enter". That is inconvenient, time-consuming and discourages usage.

2. Suppose I was invited to a meeting but forgot about it. Now I had the idea to host a different meeting and launch Proton Meet for this purpose. Would it not be nice to be reminded on the main page that I have this upcoming meeting I forgot about? This is actually something I would expect from a good conferencing solution.

3. Suppose I have elderly family members with whom I do video calls in regular intervals, or anyone else with limited IT skills. They need an easy access with just one or two clicks, not more. Having our meetings or meeting room on the main page with a "Join" button right next to it would provide that. The whole "go get the URL and then copy+paste it" is way too complicated for them, which means they cannot use Proton Meet.

True story: I wasted several hours preparing for and then setting up Proton Meet with a free Proton Account on my elderly parents' iMac and then trying to give them an easy access to the meeting room I had set up for us under my Workspace Premium subscription, which I had specifically upgraded to in order to use both Lumo and Meet (and all the other stuff I use anyway). Turns out that we cannot use Meet because it's too complicated. Whatever approach I tried (App, launch Web app from dock, launch Web app via Automation from console script, launch browser Web via Automation from console script, launch browser Web via Link) always contained a deal breaker (Web does not save meeting options, different story). I was excited about the idea of Proton Meet and I strongly dislike Facetime and my parents struggle with it, but alas, back to Facetime it is.

this is a must have, not having this is like saving my passwords in plain text if I have to just bookmark every meeting room in a web browser I don't want to forget. PLEASE add a way to save/remember/pin meeting links directly in proton meet for future meetings.

Definitely needed, maybe a singe use link to add it to the room list for the other person as well until I delete the room etc
