This has been solved.
The “find in files” boxes render extra tall in every theme (including the default theme) - but they otherwise follow the theme such as the texture. These settings are what changes the “find” and “find and replace” boxes:
[code]//
// TEXT INPUT FIELD
//
// Text input field item
{
"class": "text_line_control",
"layer0.texture": "Theme - Centurion/Centurion/text-field.png",
"layer0.tint": [30,30,30],
"layer0.opacity": 1,
"content_margin": [3,4,0,0]
},[/code]
And here’s some pictures:
Maybe I’m using the wrong settings or there are other settings hidden elsewhere?
