As some of us need glasses when using the phone, it would be great to be able to change the font size, and colour in the UI if needed.
Global minimum font-size setting with a selectiom of small / medium / large / extra-large default text size would iimprove the readability of the UI and enhance considerably the SailfishOS UX and accessibility for ppl without perfect eye-sight.

And while your fixing this (if ever), please consider to change the font rendering or change the complete font. The rendering is just awkward. Maybe it's more the Microsoft way, the Apple rendering could suit better.
