It's alright for leaving quick notes for yourself, but there's a few things which could make it better.
- Sometimes the text can be hard to see on an image background. Putting a plain-coloured, translucent background may help make the text more readable. - Not everyone can read text that small. An option to change the font size would be nice. - How do I change the text? Clicking the text doesn't bring up the options, but I don't want to have to trash and re-open the widget. Try making the widget clickable.
An okay start, but there's still a fair bit more to do.
