Advanced PDF editing in Sharepoint Online via the web browser

Interested to know if any of you out there is using another PDF editing suite tied in with SharePoint Online in the browser with all aspects of the integration present?

Unfortunately with my findings in this last week found the following in relation to Adobe Document Cloud integration:

SharePoint Online in the web browser and Adobe Document Cloud license:
1. Only editing capabilities known is very basic with ability to only add add text boxes, draw and commenting (along with collating pages and PDF export).
2. The standard tools you would find in the Adobe Acrobat desktop suite like measure, etc., are not available in the web browser.

Sharepoint Online use from the Adobe Acrobat desktop suite:

1. Sharepoint sites can be added as known storage within the desktop software. 

2. All Adobe PDF editing features are present and able to be used.

3. Downside is that every time a new Sharepoint site is worked on, need to add it to the desktop suite.
