In my search for good keyboard that support AMOLED mode, I found out about FlorisBoard which looks perfect to me. It even supports Halmak Keyboard Layout, which I didn't expect to find at any Android Keyboard.
Which make me ask, How is this keyboard not popular?
multiple languages at the same time (without switching).
extremely customizable in nearly every way.
customize long-press options for each key with multiple / list of options. For instance, I've extended the number keys row with my most-used emojis, so holding '1' gives me a pop-up with '❤️😍😘🥰', 2 gives '🙂😊😃😄', etc.
'snippets' via custom dictionary with shortcuts (typing 'xx' shows my primary email for 1-click insertion, 'yy' shows secondary email; endless possibilities). Possible with most keyboards, though.
