Works great! Could use some PNG optimizations / color options. Rated 4 out of 5 stars

Works wonderfully. Annotations and shapes and arrows are novel. Where this app could use some improvement is the addition of PNG manipulation, in the form of color reduction (various methods) and optional dithering (various methods), gray scale included, And PNG optimization, to get the smallest PNG possible on save, without having to save, then use a third party tool, such as PNGScript, PNGSlim, PNGOUT, etc... Save time uploading, save space in the cloud, and save space in local storage. All options very handy for screen captures that don't require 24bpp to convey information. Where a 4k file will suffice instead of a 400k file.
Thank you for your time considering my suggestions. I believe they will make this addon uniquely great.
