should be possible to add CC recipient/recipients to the selected docs in bulk.
so you will be able to mass select needed docs and add the CC recipients to them in bulk

Should be a complex dropdown like in word where I can choose the event/apartment and then the text + images and so on appears on a document

the users should be redirected to relevant docs once they enter specific info in forms

leave space for a recipient to specify in a dropdown field

The user should be able to select only one checkbox from all other checkboxes added on a document

Should be possible to send a document to a few people to sign, but some pages be only viewable by particular recipients.

Should be possible to share documents/templates with your colleagues, add them as editors on a document, so they will be notified (but not via email if you tag them) but inside PandaDoc so they could easily find the needed document and edit it.

The image button (the same as in Classic Editor) should be added to the top bar menu in Editor 2.0. so you can easily add images inside blocks.
