Nice! I do the same thing with custom aliases in my .bash_profile for all kinds of things, including opening various webpages, opening meditation videos on youtube and such to certain timestamps, so I think the idea has some legs. One thing I do with my aliases is have custom arguments, so like if I want to open a stock ticker on yahoo it's `yah goog` from the command line. So being able to add custom arguments might be a cool additional feature.

Good luck!
