<i>How I store my ideas now:</i> item in tasklist with project name, and a folder for it in my Dropbox with all related ideas, thoughts and material for the project.<p>As to your webapp,
<i>How would you improve it?</i> Better landing page with some info and/or pictures of what it actually does. When you create a new idea I think the private checkbox should be checked default (personal preference perhaps). Would be nice to be able to create a bullet list in the 'Notes' section. Also, when viewing an idea, the notes section strip away line breaks. This, and bullet list, would make it easier to get an overview over thoughts.<p>edit: also, when you have created a new idea, I would like a button at the bottom that takes me back to my ideas.<p>edit2: don't know if it's a bug, but it's nagging me to confirm my email adress, when I have not received an email. Maybe add a way to resend confirmation?<p><i>Suggestions on a name/url?</i> Nope, sorry.<p><i>Would you use it?</i> Seems kinda useful, I'll try it for a while to see if it's easy enough to keep updated.<p><i>Are there any premium features you could think of that would be worth paying for?</i> I would pay for a mobile app (Android)<p>Hope this helps.
