Rated 5 out of 5 stars

This is an awesome addon. #appreciation to the author!
Like another user here, I too would like to have more specific customizing options regarding individual buttons/icons appearing in the toolbar. Or perhaps at least a "wrap" option?
One reason for me is that 3 other addons that i use also place buttons in this toolbar on the top row. With those and this addon's buttons, in order to view them all I have to have a impractically wide Compose window open. Narrowing the window results in some buttons being non-accessible. There's additional room in the second row at least, but it can't be accessed or customized etc (hence, a "wrap" option might help?).
Thanks again for an awesome addon & consideration of our requests!
[btw, fwiw i'm running Earlybird (Aurora) v35 & have found no issues--tho i've not used every one of the advanced options e.g. MathType]

This review is for a previous version of the add-on (3.3.0).
