[UI/UX improvement] - New room flow

[milos-dukic]

Just wanted to point out to some UI/UX enhancements if possible for creating new room steps/procedure:

1. When clicking the add new room + button i.e. visiting /rooms/opens/new I think that New Room prefilled text doesn't give best user experience, since you have to delete it anyway, and the placeholder Name the room is sufficient enough.
2. When clicking the + button i.e. visiting /rooms/opens/new if you enter whatever text and then press back button (in the UI not the browser) i.e. <- and then on the homepage if you press the add room button +, you have the old input set, i.e. the input for the new room is not cleared when you press back.

:) Cheers!
