a2er — bastscho

Converts all words ending with an a or an a in the last syllable to er.

E.g. Wikipedia becomes Wikipedier and Jakarta becomes Jarkater.
You can toggle the functionality on and off via the button in the extensions list.

Dynamically loading webpages might overwrite the changes, which were done and revert er to a. You can always manually trigger the conversion by pressing ALT+K.
