Partials back to version 4 or Inline component edition

Dear fellows,

I´m trying to use vuejs along with Pinegrow, and having trouble with multiple files for .

Just trying to solve the puzzle, I wish to edit everything inline.

Masterpages add bunch of duplicated code for child pages (gave up)

Partials are not working with updated versions (that could be a possible solution)

Components can´t be edit inline, so when I go editing them, it lost all the layout, as BS and CSS are defined on index page (inline editing for the component shouldnt be hard to improve Pinegrow)

The last option I wish to avoid is to keep all the application code in a single page -> index.html (that doesnt seem a good pratice in an enviroment with several coders)

What options are avaliable other than that?

Thank you
