Option to disable automatic "mark as seen"

[Talkabout]

Is your feature request related to a problem? Please describe.

I am using my mailbox as a "task list" and here it is crucial to not auto-mark mals as "seen". Most mail application have an option to disable this and it would be really great to see it here too! I have noticed a closed issue where this topic was mentioned by the only thing that was changed was a delay of 2 seconds beeing added before the "seen" flag is set. That is unfortunately not enought for me.
I really like this app and would love to use it, but without that option it is not possible for me.

Describe the solution you'd like

A very simple solution: add an option "do not mark as seen automatically" that is "false" by default but can be activated in global options.

Describe alternatives you've considered

No real alternatives for me here.

You want something like this:

Here the checkbox enables it and the number input tells after how many seconds.

Dear @Talkabout,
thank you for your feature request. This makes sense. I'm not sure if we need a setting for a specific time, but a checkbox to turn the automatic \seen flagging sounds good.

[Talkabout]

For me a checkbox is fine, no time needed, not sure about other people :)

Thanks guys! Looking forward to this feature!

Thanks for clarifying @Talkabout.

I've set the feature request to 1. to develop. Beware that this does not guarantee the feature to land. The feature will only come when someone implements it. If you are a coder and interested in a contribution I can give you some pointers. We have good guides for Nextcloud app development.

Hi @ChristophWurst ,

I am a developer, yes, and I am also tempted to contribute to this great project. As I am completely new to this it would be great to get some pointers. Unfortunately I cannot say when I will have time to dig into that topic, but having a start point just in case sounds great.

Thanks!

[ChristophWurst]

Awesome!

	if (!this.envelope.flags.seen && this.hasSeenAcl) {
	logger.info('Starting timer to mark message as seen/read')
	this.seenTimer = setTimeout(() => {
	this.$store.dispatch('toggleEnvelopeSeen', { envelope: this.envelope })
	this.seenTimer = undefined
	}, 2000)
	}
