How would Google Docs update a graph in a document from an external graphics file?
All my graphs and tables are generated in some programming environment, and updated frequently. In Word, I would have to right-click every single graph, select new source file, adapt graph size... Could Google Docs do this?
Don't know about external files, but it can update charts from sheets, and you can also write a script that does it automatically, both on word and gdocs.
It does, but it has a lot of the same problems as MS Office, some worse. The scripting/macro system is arcane, proprietary, and only works in the cloud. The files aren't in an easily parseable format. You can export them to OOXML/ODF, but then you're stuck with parsing some ridiculously complex markup. As far as I know the version history is not exportable either.
Also, once I wanted to write some light math equations in a google doc and went hunting for plugins that provide just a bit of TeX-like math functionality. I did find something called "Auto LaTeX Equations", but it didn't really work all that well. It did let me typeset equations, but they came out very pixellated for some reason. I also found "gMath", but couldn't persuade it to render any equations.
