The is a section about it on the wiki, have you read/skimmed the 'build character sheet' pages there? <a href="https://wiki.roll20.net/CSS_Wizardry#Tabs" rel="nofollow">https://wiki.roll20.net/CSS_Wizardry#Tabs</a> The tabs wouldn't become a new tab among those you mentioned, but in the "Character Sheet" section you could have several tabs for different pages of the sheet. 'Savage World -Tabbed' is one of the less complex sheet you could also look at for inspiration.
