Feature suggestions: weekdays, labels, grouping, ringtone

[uok]

Thanks for this helpful app! Here are my suggestions for improvements:

• Frequency: weekdays or weekends option "weekdays" (Monday-Friday) or weekends (Saturday, Sunday) for frequency and alarm reminder helps with office / weekend work and avoids unnecessary reminders

• Labels add a label to a color, e.g. "health" for easier selection also helps colorblind users

• Grouping allow grouping (not just sorting) by labels a small divider shows label and below all habits for this label/color

• Ringtone select ringtone and set volume for reminder helps to differentiate from other apps

Thanks and have a nice day!

1. no plan to support "weekdays", because this feature deps on country's policy (e.g. in my country, "调休" is a special policy that is challenging to handle without the current year's online calendar), and one aim of this App is keep design concision.
2. see #22, "Filter" is planed for the future, but specific details are yet to be confirmed (colors filter, named color(simgle lablel), etc.), thx.
3. same as 2
4. I'm not sure that app have ability to grant these permissions on Android or iOS (as l'm not professional in native mobile app development). It maybe necessary to study the Android/iOS design specifications first.
