Flexibility to move or hide toolbar button is lost in v. 2.3. Rated 5 out of 5 stars

Updated to new v. 2.3 and reverted to 2.2 as button insists on occupying a certain fixed place on toolbar, flexibility to move or hide it is lost. To some people F9 is all that is required and button is allowed to rest in Toolbar pallet.Thank for such an incredible tool.
Edit- Fixed in v. 2.4

This review is for a previous version of the add-on (2.3). 

Version 2.4 fixes this

You are correct; version 2.4 fixes this and is already uploaded. Please note that the button may be automatically added for one last time after the update.
