A cup of coffee here, a cup of coffee there, pretty soon you're talking about a bottle of wine. Nevertheless, I thought it worth dropping 2.5 coffees to check out fsnotes, which bills itself as a "lightweight notational velocity reinvention".
I depend totally on nvALT as my general place for keeping scraps, vital information, inchoate thoughts and more besides, and the one thing that has always bugged me has been the inability to have more than one folder. Mainly, I envisage using an additional folder as an archive; notes that I truly believe I have finished with but that I really do not want to throw away because there might be something in them I need later. NvALT's blazing search speed would be fabulous for that kind of treasure hunt, but I honestly don't want currently dead notes cluttering up my view of all that stuff.
I asked about multiple folders 21 days ago and a couple of days ago the developer, Oleksandr Glushchenko, delivered just that. Definitely deserving of my support.
First impressions are that fsnotes is every bit as fast as nvALT. I haven't been able to give multiple folders a good workout yet, because I only have one big folder of notes. My minor niggle is that the display of links is different from nvALT's. A well-formed Markdown link is clickable in the preview mode, but not in "native" mode. I suppose I could fix that easily enough in my existing notes, and it need not be a problem going forward, but it is an annoyance right now that might stop me switching completely over to fsnotes.
Maybe I'll raise an issue on github for that.
