I'm in a bit of a productivity rut and whilst I suspect the issue is mainly between the keyboard and chair I'm also interested in what (FOSS) tools there are that people find effective.
One of my issues at the moment is cross managing different workstreams particularly with personal projects which are more in the "if I have time category".
I'm interested in anything that helps manage time or limit distractions or anything that makes it easier to keep track of progress/next steps for project when there may be a bit of a time gap between.
Do you know if it's possible to use Vikunja as a frontend for next cloud tasks? It does it have some extra sauce on top of caldav?
No, Vikunja has both the front-end and backend for the tasks and is the caldav provider itself.
You can use planify and Tasks.org as frontends to manage Nextcloud tasks on your computer and phone, respectively
