a suggestion, placement and extra characters when depress and hold ...
If I were to depress and hold down 'x' on my SwiftKey Android keyboard, I am given five currency characters. It would be great if those currency characters could be rearranged. (I realize that the choice of language determines the default single character that is displayed above that 'x'.)
Also, I often use a back slash. When I depress and hold the 'm' on my SwiftKey Android keyboard, I am given the forward slash. I have to travel some to find the back slash. :)
It would be great to have both slashes joined to that 'm'. I can think of several options here. You could free up several keyboard letters for other special characters by pairing < and > on one letter instead of using two letters.
At any rate, I've been using your product for years and love it. I hope you consider my suggestions.
