I selfhost Vikunja on a small 1GB RAM VM. It has views for list, table, Gantt and Kanban (I assume that's what you mean by not manually reordering?) You can setup reminders for your tasks like any project management tool as well.
You can access its web interface via port 3456, so no syncing or external app is needed, it's all browser based. Of course, you can setup a wireguard VPN to access it anywhere.
They'll never encrypt my 2000 DVDs!
I understand this is a non-issue for your home network, but as I understand it, the real risk is when using a VPN in a public and untrusted place (e.g. a coffee shop) as most teleworkers do
I was always curious about those. Surely they can't be faster than computers right? I mean, whatever computers they have in the 24th century.
On a sidenote, what theme did you use for Kubuntu? I've scoured the webs for all kinds of themes and none do it justice.
When will it stop? No really?
