Several features are required.

1. Write text
2. Fluorescent pen
3. Filled squares and circles

I would have asked for hollow circles and ellipsis first, then ordered these 1, 3 and 2.
Extra ball: rounded corner squares

Also, keyboard shortcuts for colors, etc... (unless there is a config.ini way to do it)
Great app by the way.. Thank you.

@iyagicom

1. Describe how you would like the feature to work.
2. I will check that.
3. Should be easy to implement, but can you extend the idea? For instance, some use cases.

@silopolis
Can you give me examples of use cases for hollow circles and ellipses? How do you think it should work? Just simple shapes or something more?

@daveprowse
Good idea. Will add it to the list.
