Thats actually next thing to implement in the list. Audio caching, the feature is on it’s way!
And regarding the fonts, I actually wanted to stick to the native fonts — But San Fransisco of iOS and Roboto of Android vary too much in their sizes. That is for the same font size it viusally there is a huge difference. This is causing all sorts of UI problems. So for now I solved the issue by using a custom font in both OS.
Would love to stick to the system fonts. Needs some strenuous code tweaking though.
