Looks really cool. I tried to add some CSS (inline/local/from CDN) but it didn't work. If it worked I would use it instead Notion to make some nice looking notes. Some feedback - would be nice to have shortcut to source. Portable version have unnecessary folders (sciter\sciter\sdk\bin\32\files). When I have one note (tilted 'new') opened the title is written vertically as:
N
E
W
If I change title or create another note then it's written horizontally.
