If you want to try HelixNotes, be aware it overwrites the front-matter of notes you open (view only, no edit needed).

Hi ArkHost,

Obsidian user here. I tried HelixNotes for a couple of minutes and here's my feedback:

• I like that you support compatibility/converting Obsidian vaults. I wish you would at least support Obsidian's wiki links directly. I won't convert all my notes just to try if I like your editor.
• View mode doesn't seem to really do anything. Ah wait, seems like I can only click links in view mode (no visual distinction between normal editor and view-mode apart from the tiny view mode badge). But that opens the linked note in my default .md viewer, not the HelixEditor itself. IMO view-mode should be visually distinct and also work together with source-mode (so I can edit in source mode and then click view-mode to see the rendered note).
• I like the simple look, although the UI is not as polished compared to Obsidian.
• I need Math support ($ ... $).
• I hate that you update notes front-matter even if I just view and not edit them. Only change notes I am editing myself. I just had a look and now you changed the format of my notes. Re front-matter it would also be good if that behavior is documented somewhere.
• I closed my vault (clicked on the folder icon in the top right) and wanted to reopen it, but got an error: Failed to acquire LockFile: LockBusy.
• The graph view opened but stayed empty.

Feel free to use my feedback however you want, or don't. Personally, there's more than one deal-breaker for me to switch from Obsidian to HelixNotes, without even considering the nice-to-have features added by all the plug-ins. I recommend you to listen to people who are more likely to use your editor than me, or are already using it. I hope my comment doesn't come over too negatively. I tried to give honest feedback why personally I won't use HelixNotes anytime soon. I wish you all the best.
