Looks good layout. Will make it easier for user to work at better speed.
Only concern I have is that any section below last tab is not visible if you click any tab that is prior to last tab. User has to click last tab for the sections to be visible.
Irrespective of which tab you are on the sections after last tab should be visible. It’s framework issue here. Seems there is no closing of tabs like what you see on websites on WordPress, Laravel etc. Hope Frappe team will look into it.
