TTMSFMXMemo cannot handle proportional fonts. A properly implemented TMemo component is sorely needed as after 4 FMX releases, Embarcadero has still not delivered FMX as a usable desktop framework. I could certainly use a decent TMemo/TRichEdit component for Firemonkey and I hope you guys could deliver it. Otherwise, I would have no use for Firemonkey and obviously I would not remain your customer. This is a show-stopper for us. With the frequent releases and number of target platforms, it is not practical for a small group to repeatedly fix the implementation.
This feature will not be implemented.
