Yes! I’ve been trying out the WikiLinks feature, it works quite well (though it’s auto suggest can be a bit “dumb” at times suggesting longer item names when a shorter one will do).
A big difference however is backlinks - Roam automatically creates backlinks to every file that another references. This would be very useful in DT and currently requires a slow and janky scripting process. Roam also supports atomized linking - each paragraph inside its markdown-style files is given a unique UUID to allow for granular linking (and back-linking). Creates a lot of interesting knowledge-management possibilities.
As far as Markdown is concerned, for sure not looking for a full do-everything editor (can use other apps for that). More just asking for Markdown to be equal with RTF as a first-class citizen, EG for templates and defaults to be equal between them. For example, right now if I want to use markdown in the daily journal workflow I have to hand-build my own template. No big deal for one workflow… but added up to all the possibilities in DT and there’s a lot of places where RTF is the default and markdown has to be manually edited.
And prism - yes! Understood, it’s just for rendered formatting. Still can’t get it to work though and something like this which is a common use case for markdown (code snippets etc) seems like a good candidate as a possible built-in option for a knowledge management app with as much power as DT
