The Create a Character option could be somewhere in the characters menu.
Then when you click on the option a white box appears. Starting on the right, the editor option, when selected, allows the user to click any shape and change its form.
The shapes can be selected and you can easily create a circle/square/triangle etc. by dragging across the screen.
The scissors are there so that if you don't want a shape, you can delete it by selecting the scissors and then clicking the shape you want to delete.
The more colors option allow you to change your current color and when clicked a color wheel appears.
The current color option displays what your current color is.
Finally, the select option lets you to move shapes around without accidently making new shapes. It acts like a cursor.
I hope you consider adding this feature to the next update! -torithecrafter
