I have discovered hackmd.io a few months ago and started digitalizing my massive mess of handwritten nodes together with all the terrible notepad/word mixed notes into one big personal "wiki" of knowledge. But I ran into a problem. HackMd can only handle ~50k characters before starting to lag and 100k characters is the limit per note, this doesn't even fit my one summary/tips note on one programming language. Do you know any alternatives? I really like markdown, since all of the notes look clean and organized, I can insert pictures and link to websites easily, but also love to work with them online, since I have to switch between 3 computers between university, home and my laptop.
