1. I'll check the search tonight and add some tests to cover it, thanks for letting me know.

2. Agreed regarding the design - could do with some improvements. I'll tweak it.

3. The reason there's a notes icon is because I'm planning to have other icons there too (I'm considering a few options but perhaps bookmarks, contacts, files, etc - that kind of thing). Doesn't really need to be there now, admittedly, but it shouldn't be too long until there are other sections.
