Button hitboxes too small

### Your use case

Clicking the send button often fails because I miss the hit box slightly (fat finger). I suggest making the hitbox bigger and maybe increasing the visual size as well .

Clicking on the room title is a similar problem, the hitbox should be the entire top bar, not just around the text.
