Improve typing notification text
Description
Assigning to Mircea as the last active on Spark.
It shows typing notification with some crappy super small font. Psi shows this in the titlebar of the window. I think it was more elegant to show composing icon instead of a text message. It can be showing in the tab title, or somewhere near the chat input area, i think the icon would look nicer and cleaner.
