I like the clean interface and as you can see, you can have other pinned panes open for navigation, or sub menus (you have a lot of flexibility on how it looks). I have Obsidian locked in preview so I don’t accidentally change a recipe (a frustration I had with apps like Bear where it is too easy to accidentally edit). I only use Obsidian for my markdown cook book.
I tried DTTG (which I use for everything else!) but was limited to the group/document hierarchy on the left and found the wiki links can play up. Sometimes clicking through document wiki links, on the third or fourth document the links stop working and you get [[name]] instead of a clickable link (Stopping and restarting DTTG resolves it, but it is annoying). FYI All the markdown documents in the cook book are uniquely named, so it is not two documents with the same name that causes the links to stop. Could it be related to the number of documents within the cook book?
