Sakay.ph no longer uses Google Maps for places search. For some cases, this makes looking for certain locations more difficult. This bookmarklet was made so that you could search for your origin and destination in Google Maps and then go to Sakay.ph to get routing directions.
Note: I tested this on desktop Firefox and Chrome. It does not work on mobile because Google Maps has a different url scheme for it for some reason. This will also likely break in the future when Google decides to update the url scheme.
