make colors more user-friendly.
"Save" button has no color without hovering --> include color to make it more obvious that it is a button

Generating buttons that consistently match the suggested color theme can be a bit complex. As a first step, I recommend exploring whether ImGui offers different ColorButtons or a method to customize button colors based on their type (e.g., cancel or save). Otherwise, relying on manually pushing colors before each button is susceptible to errors.
