Thank you for posting. First, you do have the option of switching your application from the Alpha or Beta channel and staying on the Stable channel. Please open Preferences > System Tab and switch your update setting over to --> ok
Next, we're happy to help troubleshoot/discuss these issues with you.
First, regarding Outlook: Unfortunately, Microsoft made supporting drag and drop from Outlook quite difficult and has changed the APIs required to make it work several times. This is not a trivial feature to implement. However, there is a good workaround. Simply open a folder for the Thought where you want to attach the message then drag and drop to that folder.
-Right-click the Thought
-Open Thought Folder
-Drag the email into the folder
Alternatively you can drag and drop to your desktop and then drag from there to TheBrain.
More direct support for drag and drop from recent versions of Outlook is something we are planning for a future release of TheBrain.
We do have an open ticket to review the document preview message you received. Does the preview feature work on the second attempt of the same document?
-—> unfortunately not.
TheBrain 9 should definitely be running faster than v8. What type of slowness have you encountered?
—-> e.g. Change the Theme
You are correct that version 9 Brain databases cannot run in version 8. The application architecture is all new in version 9 and the databases that v9 creates are not backwards --> ok
I'm not sure what you mean by "Notes in TB9 , a so called "unreasonable imposition"" The focus of notes in v9 was the ability to create easy, consistent content. Further development and options within the notes (and all aspects of the software) are planned for future --> ok
And finally, "lack of export". What type of export were you hoping for? We've recently created a video tutorial that demonstrates some export options at https://www.thebrain.com/support/tutorials#importing-and-exporting
