Add a feature to configure DND mode

[akashnimare]

We have a basic DND feature in the left sidebar which activates the DND mode and to deactivate user need to update it manually. It would be great to have something like -

• Enable DND mode for X minutes/hrs/day

and then automatically handles the notification setting after the DND time gets over.

Two things we need to do here -
a) UI/UX - I think we can show the time within the tooltip itself
b) How to calculate the DND time since there could be multiple cases like the laptop is switched off/sleep etc.

To implement this I have/had a rough plan in mind:

• First we should create the UX/UI in a new branch or that only shows up in development mode.

• Then, once we have the UI, we can set up the turn on/off thing per input provided by the user.

• Lastly, we should save in JsonDB the end-time of DND time, so it just a one if statement on the start of the app to turn it off or schedule a timer if it not done yet.

For step two, we can use something like node-schedule to do turn off the DND button after the specified time, in which case if the app is closed or device shut-down it will not work. Which we will need to cover in step three.

I know this is the repository for the electron app, but can you clarify why you see DND as an app setting rather than a profile-setting?
Imho it leads to confusion and unwanted behaviour if there is a DND layer above a profile setting.
If I don't want to be disturbed, then I do so in my online status which should then reflect across all apps.

similarly if i want to receive notifications again, I should be able to do so on mobile and the changes should reflect on desktop.
that's why I think this should be followed further (only) as a profile setting and not as an app setting.

Thanks for the link. As it seems the main reasonis this statement by @timabbott

I think it's actually probably useful to have a desktop app feature for this, because if you're in multiple organizations, you kida want to be able to turn it off for all of them at once.

I agree that this is a very good point, which i didn't consider before.
I would still prefer if this kind of status-change would reflect consistently over web, desktop and mobile.
How to communicate over multiple organizations a common state - I have no idea.
An approach to change an additonal notification-status in each logged in organization would be an option, maybe.

For the UI thing, we could show something like this in the tooltip -
