I am familiar with VSC a bit and have given Dendron the once-over;
I played around with OBS / Dendron and what I noticed is for the notes to appear in the Dendron Tree the notes must be at the vault level not in any folders. I guess this is where the Dendron hierarchical note structure comes into play. So in order to use this feature in Dendron; #1 the OBS files need to be free of any folders; #2 all notes need to be written with the “Note.Subnote” naming convention inside OBS.
Why would someone want to use the Dendron workspace for OBS? I realize the Tree feature some might find interesting, but I think that is similar to setting up folders in the OBS Explorer. The Explorer might not be as clean as using the Tree but it effectively accomplishes the same thing I believe. Having notes inside the Dendron vault seems a little messy with the admin files in there such as .vscode root assets json yml and maybe one or two more I don’t think these can be moved elsewhere? I don’t know Dendron well but I suspect anything else it can do can also be accomplished using a blank workspace with a few extensions without having to fool around with the Dendron vault. I am not making a case for or against Dendron just understanding why someone would want to incorporate OBS with another program that does essentially the same thing and less. I myself use VSC with a few extensions to simplify editing and navigating where OBS might be a little clumsy so it makes OBS more appealing to me. So what benefit would be gained by opening OBS in a Dendron vault and merging two programs?
