You can add a profile picture in your Pebble+ account by hovering the mouse over your name on the Homepage and clicking Edit. At present it is not possible to remove or reposition the panels on the homepage. You can create your own banners for your Pebble+ assets.
Using the Template Builder you can create templates of any kind (like the ones in ''PebblePad templates''). You can also create your own workbooks using the Workbook Builder.
