I couldn't figure out how to customize it(change the size, color...) of the menu icon (3 horizontal lines). It's small, I need to increase the size.
I saw this question How to change menu icon size in Codename One Toolbar? but it's too old and I didn't find the 'menuImageSize' theme constant, although it appears in the documentation.
It should still work fine despite the age. You can edit the value in the combo box. Notice we recommend working with CSS nowadays.
