You will prberly get a few come in and say you dont need a App like
Appcleaner or
AppTrap BC when you drag something to the trash. There are a few little files that will be left behind, and if your anal retentive you want to clean them out. I say to them over time, like years with all the Apps we install and then get rid of those little files start to build up.
But to andswer you question, yes you can just drag it to the trash.
You will be left with those little files, but if you want to have to whole kit and kerbuddle gone i suggest you use a App like i linked to.
On trashing or uninstalling, if ANY App has a uninstaller .pkg it is recommended to use that in stead of something like Appcleaner or Apptrap. I personally have AppTrap installed and it sits in the Preferences, its out of site and unobtrusive, and the way it works is when you drag said App to the trash it will then ask if you want to move any associated files/folders as well ...
Its as easy as that
