Successive paragraphs indent in email composer (HTML)

Hello, I’ve just setup eM Client, which looks great, but this only problem prevents me from using it :

In the email composer window (HTML), when indenting a paragraph (via the icon bar), successive paragraphs created by Return key are not similarly indented, as is usually the case in text processors and email clients such as Thunderbird that I’m using now.

Maybe there’s a way to do it ?

Yes the only way i found to Indent any paragraph is to (select the text after typing it) and click indent.

Note:- Interesting though if you just press indent and press enter without typing anything, the indent stays there. So its only when you type after the indent and hit return that the indent is lost. Strange.
