I'm very happy with this program, the GUI isn't the most elegant but it does the job.

I don't think I'd describe the GUI as 'bloated' though... it's actually pretty minimal. I think the screenshot on the github page makes it look busier than it really is (e.g. the sidebar can be hidden, and you'd usually be using it with a larger window size).

I find the program to be very powerful out of the box, so I haven't had to customize much (the customization is just icing on the cake IMO).

I use this program every day at work as my personal knowledgebase for my technical support notes (and also for taking notes on phone calls). I have thousands of notes and this program handles it much better than anything else I've tried. The powerful tree structure, fast search, and tagging system make it really easy for me to quickly find what I'm looking for.
