It's recommended that you use headphone while using push-to-talk. 

Both features are work in progress, and will be available in the coming months.

You will see it in April, stay tuned....

The iPad version has a built-in eraser, the Mac OS version doesn't. You could  still accomplish it by selecting the object with the delete key on Mac.

Yes, it's indeed a bug on the Mac version, we will be fixing it in next release.  

Thanks.

Are you using BaiBoard on Mac or iPad? 

Resizing selected element is already supported, please give it another try. Rotation could be supported in future releases. 

I assume you are using BaiBoard on Mac rather than the iPad version. 

Request noted, we will consider adding this one in. 

Yes, it's indeed a bug which we intend to fix in the coming releases. 

The short term workaround is simply cut and paste object (select object and long press) to re-arranging the order until we officially fix the bug. 

Please stay tuned. 

Yes. It's indeed a bug on Mac OS 10.7.x.  We have fixed it and submitted a new version. It should be available on App Store in a couple of days.

It cause of the issue is an API inconsistency between 10.7 and 10.8, we were not aware the existence of inconsistency between the two. 

Thanks.
