The first productivity tool I ever encountered, I still love this launcher because of it's single-modifier-tap shortcuts. For example, to open Chrome, I type "⌘, C". It's simple and fast.
this is the first app I add to any new mac Have permission to do so on. I really only use it as an app launcher, but I know ir can do far more; I've just yet to dedicate the time requredto learn it.
