Luck - thanks for considering the white background option - that is something I have wished since the first time I used liqbase.
For the lines - maybe same as Xournal is fine with me - but again maybe a toggle botton to turn the lines on or toggle it off would be great - since often time someone may wish to used a lined background (for clean writing), and some may not to fit in more writing in one screenful.

Also your consideration of a configuarable startup modules is very welcome. That would make liqbase more useful (considering its fast startup).

One input from me - I know liqbase has great potential as a tool, but I would also like to see the icons and buttons and fonts designed a bit more professional and well designed to give a overall look of a great application. I understand you might be concentrating on the actual implemetation part of the app and its features - but maybe someone could chip in with the graphics design part of it - just a suggestion.

But as a note taking app, even I like liqbase best as a efficient tool (though I like Xournal as a better looking tool).

(I know I am rustling up a hornet's nest here with the design and looks vs functionality debate again).
