In Experience Builder Apps for mobile phones, the interface is small, so space is at a premium. The default pop-up has a lot of white space, including an entire line just for the "Zoom To Selection" icon (see screenshot below).
IDEA: Allow for customisation of - or provide Templates for - the pop-up layout.
1. Enable the Zoom button to sit in the title bar (or elsewhere in the pop-up), alongside Dock, Collapse and Exit.
2. Assuming complete customisation is difficult, provide some templates for the Pop-ups as per Lists. Include options to minimise line spacing/white space, and choose which actions are allowable.
3. Make field widths adjustable.
