Remove 'Main Content' Tab

Furthermore, am I able to change the order in which the tabs are displayed? For example, I’m currently converting a static HTML site to WP using your plugin for the many different editable content areas on this site (it’s a single-page website). I’ve registered each block from top to bottom, i.e. logo block, h1 block, top sidebar block, bottom sibebar block, text block 1, text block 2, footer contact details block, etc. When in edit page mode, the footer content block tab is displayed first, with everything in reverse order of the natural page flow. This can be confusing for a client when editing the page.

Thanks
