OpenTasks Customer Insights

1. It is really annoying to have all other apps using Mo-Su week and only this one uses Su-Sa.While not exactly good, unbelievably this app seems to be the best option for syncing caldav tasks with Nextcloud.

2. I'd wish an option to set default values for new tasks, recurrence options, and the ability to snooze a task for anything else than a day.

3. The only thing I miss is being able to set up recurring tasks, but that's a limitation in Nextcloud Tasks itself.After 24h of use I'd say I'm surprised by so few options.

4. It will be amazing if the developers could add these two features: Night-mode (or dark theme), and a task tracker feature wherein the app will simply calculate the avg progress % per day required to complete any particular task and show based on that whether the user is ahead of schedule or behind schedule.

5. Thanks!The app works fine for syncing tasks from CalDav server that the calendar app, I'm using, is not capable of.

6. But never mind, I have my workarounds and protocols, and it is a really excellent app, I'd give it 6 stars if I could.Worked great for the first month, suddenly stopped allowing me to add new tasks.

7. Some theming or colour options other than the default green.This is a basic task manager at the moment, it doest even support task recurrence yet.

8. What is critical is that after phone restart, I automatically get a barrage of notifications of all completed tasks in history.

9. For five stars please add: Option to use checkboxes next to tasks instead of swiping.

10. Categories and recurring tasks being the most notable.

11. In my setup, I usually need to snooze it 15 minutes but right now the only option seems to postpone an entire day which forces me to enter into deep editing.
