Collabora Presentation and Spreadsheet features

Can someone confirm for me if these features are not available?

Presentations: There seems to be no way to add in a custom dragable textbox. This is probably one of the more important features of an Presentation/Powerpoint software and it seems to be missing.

Spreadsheets: Is there no formula builder or tooltips available, or ways to search through available formulas? Are you supposed to memorize the syntax of every possible formula? How do you know what formulas it supports and doesnt support?
