Missing inline formatting is a Gutenberg killer!

[burnuser]

Is your feature request related to a problem? Please describe.
I use regularly inline formatting - for single words and even characters in paragraphs and lists - like:
Text-Color, Background-Color, Underline, Font-Family, Font-Size, Justify, ...
Inserting: special characters, unformatted text, Nonbreaking space, Subscript, Superscript …
Until now I can do this with TinyMCE (Classic Editor) and the help of plugins like TinyMCE Advanced (more than 2 Million users!)

But in Gutenberg there are no such inline formatting possibilities and the toolbar is not extensible by TinyMCE Advanced and other plugins. And font size and colour for a whole block (and only paragraph!) is no sufficient replacement for real inline formatting within a block!

To be honest, without real inline formatting I can't even imagine to use Gutenberg!

And at least more than 2 Million TinyMCE Advanced users have the same problem ...

Describe the solution you'd like
1.) Bring back inline formatting from TinyMCE
2.) Make a reduced/full inline formatting set optional => for those, who (don't) like/need real inline formatting.
3.) Make toolbar extensible for plugins

Describe alternatives you've considered
a) never ever update to WordPress 5.0
b) use Classic Editor for the rest of my life
c) use Gutenberg, but only classic block (crazy!!!)

@ellatrix if I understand correctly Justify can be added back as a plugin using Format API - #10209?

@burnuser @Misiu You can use EditorsKit plugin. I've added the missing Classic Editor formats to Gutenberg block editor. Thanks!

Gutenberg now also includes inline text color.

[Misiu]

@Soean but does it includes justify?

[phpbits]

@Misiu With EditorsKit plugin, yes.
