I have taken a break from active participation in the forum from October 2017 to about now (October 2018) but I expect to be far more active over the weeks between now and the end of the year.
I expect to spend some time revamping the issues list on github and creating small, self contained issue descriptions that could be worked on by fairly new contributors in an independent environment. The key to this is a good desription of the desired function and its interfaces. The use of SVG file as background is a good example of such a small project. I intend to write it up in what I hope will be a way some potential contributor will find manageable.
Thanks again for your suggestion and please check by occasionally. I hope to also correspond with you further about what you have already done with the seamly cloud and related tools
