If you're wondering what's been happening with Notes in the past few years and, perhaps, haven't been in a position to upgrade past version 7, then I definitely recommend that you take a look.
There's a lot of good stuff there already on Day 0, including such tempting tasty topics such as: -
- Adding a web search engine to the search bar
- Drag a message into an EML file
- E-mail conversations
- Calendar overlays
with the promise of more to come.
If Doctor Who can make bowties cool, then try wearing a bowtie when you use Notes.
