I was out of network since Dec 28th and couldn't get back to you.
There hasn't been any activity on the GitHub as I am currently in the process of rewriting the whole thing to add flexibility to the whole system and the development cycle of the product.
And I am prioritizing the finish this...
Yes, it was a silly mistake from my end. Should be fixed on the next version.
There is no "best" self-hosted image optimizer as there is only one self-hosted image optimizer per image type (JpegOptim is for JPEG, OptiPng is for PNG and Gifsicle is for GIF image type).
More formatting options will be added on later versions. You can now do some ugly hacks like using template conditions.
Support for [bd] Widget Framework is yet to be added.
As you can tell from my late response, my availability is still in the low. And will like that till December 13th when my current semester ends unfortunately.
The add-on still handle only one currency at the moment.
Currently this feature is missing. I am currently in the middle of reworking the entire rating system and this feature will be included once that's done :)
