PS 1.7 - HTML / CSS editor

[superskyman100]

Hello,

I'm on PS 1.7.6

I'm trying to edit my 40 automated Emails * 6 translations....  and.....

DAMN !!... IT WILL TAKE ME AGES TO DO SO WITH SUCH A POOR INTERFACE...

Anyone knows a little toolbox i could add to the poor PS 1.7 native editing 'interface', so that i would.t have to enter the code just to center my text ???.... 

I know this : https://addons.prestashop.com/en/administrative-tools/20940-supertinymce-pro-professional-text-tinymce-editor.html?ab=1

But clearly, out of my budget...

Any free little tool ???...

Thanks guys

Have a great day !
