For us Windows users, 60-100MB software installations are not much… even my Notebook software are bigger than that…
But I do agree that it’s good to try to limit the size… But 50MB extra for great functionality are not a problem for most researchers, when other software packages takes 4-500MB and some of them up over 1,5GB.
I have photography and video software on my computer that each takes 1,5-3GB when installed…
