Add reminder setting (in addition to the deadline setting)

[waazdakka]

Describe the solution you'd like
Actually we only can add of the due date. I would like to be able to configure a reminder alert, in the event that I cannot perform a task at the moment but I wish to have a reminder on a specific task

Additional context
If you have an event on April 20 but you have a few things to check before that date, for example that everything is ready on April 10, having a reminder on this date can be useful, instead of having a second card for this reminder.

This may be done in the form of milestones with reminders inside.

What kind of reminder do we need?

Just discussing things:

Set a date:

• works independently from due date
• with used datepicker it seems also quite easy to also set time

• guess you also use due date, and the card should be done later, you need to change due date and reminder date separately

Set x before:
dropdown example:
1h
2h
6h
12h
1d
2d
3d
5d
1w
2w
custom

• faster to set, don't need to get a fast overview of calendar
• also latest option or personal setting option could be remembered, to even faster/smoothier set that reminder

• x date should be referenced to due-date (not create date), but then it's not working without due date
• reminder date could be on weekend/non-working hours (pls don't automove to mon-fri, there are also ex. ngo working on weekend)

I also guess, every assigned person gets a reminder. Also possible to set reminder by person, and also add for "all setting".

What about multiple reminders?

If this get's implemented, i guess a push notification seems to be adequate.

Wouldn't it be transferred to activity app, where you can choose if you wanna get push and/or mail notification?
