Similar happened to me and my OP a few months ago. Decided to buy/try a refurbished OP9 from Iode with their version of LOS pre installed. Very happy so far

Mull, Fennec on mobile and Librewolf on laptop

I’ve used it for 3 months. Really like it and the options it provides. Very useful resource althougg I’m not self hosting yet. Lack of collaboration an issue but I believed its on the roadmap

Yes MD can be used or just enter text into their pro forma objects

I have been using anytype.io for a few months and love it. Best thing is it’s “local first” so stored on your own devices, just synched online.

I have both. Had Bitwarden for many years but trying out Protonpass as an alternative. Bitwarden still the one for me at this moment

Thank you for your comments. Helpful
