I administrate my MySQL database by Adminer 4.1.0. Now I wanted to add a column to an existing table and I didn't find how to do it except typing ALTER TABLE into the "SQL command" window. Lack of such a basic feature is not crippling for me (I know SQL enough), but still annoying. So did I miss something, or is SQL command window really the only way to add a column to an existing table in Adminer?
