give possibility to change size of font in widget and its color of background
Not the widget, font size inside the apps itself is terribily too tiny.

I haven't figured out how to change the font size on the Fire.
Be able to make individual lists different colors. Customize my preferred color coding - background or letters
It is already possible to resize the widget. That is standard Android feature. Just Google "android resize widget"
We are working on updating the widget look and feel and have it follow the color theme of the app itself (as set in Settings)
Would like to have widget color choices and transparency values. Need ability to resize widget
