New features

[LedZeck]

I've got some ideas for (small) features:

1 - More available angles to rotate gradients;
- Basically, a dropdown with additional diagonal angles (15 and/or 45 degrees) options

2 - Color amount filter:
- Buttons to select only gradients with the specified amount of colors (2, 3, 4, 5...)

3 - The # remove button.
- In some cases we don't need the # on the Hexa value. And could be an option remove that character from there.

I could implement these improvements, if would be approved
😃

I would like to add a new feature:
4. There should two new sections -
a. Circular Gradients.
b. Special and Mind Blowing Gradients.
