I see onlyoffice uses different text editors in the different modules, for example in email and in community.
In community you can not indent paragraphs or add quotes for example, while you can do that in email.
It should be nice to add features like view source code and choose different paragraph formatting.
Why not use one uniform text editor? (with advanced options you can turn on/off if necessary)
Also it would be nice to be able to drag and drop images in the text area, and to paste images from the clipboard directly in the text area (for example screenshots).
