UX: Contact/MUC actions should not be in chat toolbox
The button to invite friends to a MUC, and the hamburger menu for PM/MUC is currently in the text composition area. This is not very intuitive because:
- the '+' button in this context (to invite contacts to a MUC) doesn't have a clear sense... some friends of mine think it's to upload a file (like in "cloud" storage UIs)
- hamburger menus are not more or less user-friendly (there's UX studies about this), but people who are used to them understand they bring more actions/options in a specific context ; in the context of the chat area, it's not clear what it does (that for example, you will find contact details there)
These actions are not related to the message you are typing, but to the chat as a whole. From a UX perspective, i think they belong in the chat topbar where the chat name is located. This makes discovery easier, because finding a small icon in the bottom-right and understanding the meaning of it is not ideal.
