customizing text editor of the composer

Hello,

waouu ! EB5 it's just amazing ! thanks to all the team

I didn't found where to customize the composer text editor :
- i don't want to let my users changing font and size
- i want to include a dropdown to choose a style : H2, H3, paragraph...


if it's not possible, please say me that it's in your close future plan ??


I have one more suggestion :
When the user is starting editing text or image in the composer, i would suggest to auto switch the tab (in right) from first tab (post) to the second one : block tab...
like this it is much more easy for the first time user to understand that he can use parameters there or insert blocks...


thanks in advance for taking care of that
