add an indication that more rooms can be found by swiping right

[uhoreg]

as it is not always obvious depending on the device resolution, e.g. in https://matrix.org/_matrix/media/v1/download/matrix.org/XwmHUAuKDmbUgNFEabKtWuCB Maybe add an arrow or something. See discussion starting at around https://matrix.to/#/!DgvjtOljKujDBrxyHk:matrix.org/$15130082454748470vWaQC:matrix.org

Let me add:

Would you add an option to list users and rooms not in this (current) way...

PEOPLE
1 2 3 4 5 6 7 8 9 10

ROOMS
A B C D E F G H I J

...but in this way:

PEOPLE
1 2 3 4 5 
6 7 8 9 10

ROOMS
A B C D E
F G H I J

...so that all PEOPLE and ROOMS listed in more than one horizontal line so that the user is not forced to scroll horizontally?
The current way (at least in Riot F-Droid v0.7.03) is quite confusing because users are more used to scroll vertically (as they are used to do reading a chat: scrolling vertically). More than one time people asked me: where are my contacts and rooms adding more and more contacts).

Thx!
