Could you allow us to change the color of the buttons through a custom in-app color picker rather than having to enter a hex-code? It'd make the process so much easier and user friendly, since I (personally) don't prefer the preset colors for the widgets.
Additionally, could you allow us to change the color of the vector icon inside the widget? White by default for sure, but it'd be lovely if we can go deeper into designing the look of the widget ourselves.
I consider homescreen widgets legitimately the most powerful thing the app can do, making my computer perform tasks with a single tap.
They do look a little ugly as jagged rectangles though, so could you please turn them into circles? Or perhaps even rounded rectangles. Something a little more graceful.
