We are always eager to know what our users are thinking about our products. And you should remember, Avro Keyboard is not only a keyboard utility, it is an bangla interface. The possibilities of this project can be extended to far from a simple Bangla typing software.
Think deeply, you don't have to pay for this! And you don't have to pay for Avro Keyboard too! Just ask what you need in the software and you will see that is going to be implemented.
Ask for anything, a converter for your old documents, more fonts, more features, any new keyboard layout etc. We will measure your request to set priority of the futute tasks.
Good luck.
