Version 1.2 released.

Changelog:

-removed the username change feature,

-added username autocompletion; if you type at least 3 letters of somebody's username who is online, a small tab will appear with a suggestion to autocomplete username. Click enter to accept autocompletion. Use up and down arrows to choose between suggestions if there are more than one. Currently the tab is not clickable.
