customizable special character placement-long press
Please allow user to place characters in place for long press on several keys.
This has been suggested for Android (by Matt Winans).
Customization is important because there are many special characters, and there is large variability in the characters to which different users wish quick access.
The concept appears in Blink keyboard, but their implementation is terrible.
In case I didn't make clear my request, here's a workaround I use to implement my request using standard iOS keyboard:
If I type "<" and then "=" (without quotes), text replacement enters "≤" (without quotes).
I'd like to be able just to long press a key which has ≤ as a optional symbol on it.
