I use Evernote a lot, for all sorts of things. Here are some improvements I would love and frustrations I've experienced.
- A clever and clean way for tracking changes and additions for hand written notes.
- Evernote allows adding hand written notes, but they go page by page, which is frustrating when notes or designs span longer lengths. Allowing a continuous stream of hand writing would be great.
- Better merge resolution. When you happen to make a change on the web (clip a web page for example) while writing notes on the iPad, I often lose notes.
