Almost a year has passed, and now it’s a suitable time for me to look back, and to look forward.
Two new packages I consider finished. One is PackageMaker.jl (discussed above under the name PackageInABlink), which is a GUI wrapper around PkgTemplates.jl. Another one is ShareAdd.jl - a tool which IMHO could be useful to most Julia users.
I have already some idea about what could be a next project. However I’m open to your suggestions. E.g. maybe somebody has a project where I could take over some part (not too complex, not too boring, not too mission critical, not too unimportant 
).
P.S. Data Science is not my field of expertise.
