Is there any way to highlight the active field with a different color? Sometimes it is hard to tell which field is active especially when you have a large number of buttons.

You could highlight a field easily the moment you start typing into it but it would require a bunch of extra fields in your db. You can use a global field to hold a light yellow box. Then you have to use another field for each field that you want to highlight. Put it behind the field that you want to highlight and make it a few pixels larger than the highlight target. Set it to be a calculation that basically says

if field_to_highlight is not empty, then highlighter equals the global that contains the color.

It will highlight any field with a border as you start to type into it.

Hope this helps,
