Disappointed at loss functionality

I’ve been using Mailpoet2 since early 2015, and I had high hopes for the new Mailpoet3, but
* it does not work on Microsoft IIS
* it does not work (yet) on multisite
* no left or right alignment of images in the newsletters, only centered or full width
* no option to choose image size
* no option to show text next to the image

Also some features are now only available in the pro version, like automated emails to new subscribers or disable the Mailpoet logo, although I do understand what it takes to develop and maintain a plugin like this.

I’d be willing to buy the pro version, and I’d even be willing to switch to a non-IIS provider, but I’m really very disappointed at the loss of the image options. So I’m not sure what to do now, apart from sticking to Mailpoet2 as long as I can, and hope these functions will return in Mailpoet3.
