More customization options for each individual buttons

[OneDEV135]

Is your feature request related to a problem? Please describe.

No, just that macro deck could have been better this way.

Describe the solution you'd like

Make each button more customizable.
For example, the ability to add a border to the button and change the thickness and colour.
Or, the ability to change the size and colour tint for icons.

Describe alternatives you've considered

Edit the icons with an image editor (which is pretty inconvenient when an icon pack has a lot of icons. )

Additional context

Some icons are too big to fit text underneath.
