+ Great idea.
+ Does work on ElCapitan.
- Pricing is wrong (it's $10 not $4).
- Tyler is selling off the app and copyright as well. So future is in doubt.
-Could be prettier. The dialogue box is awfully big. While simple the design is not elegant.
+ Easier than setting up something similar in KeyboardMaestro.
- App is huge 1.9 MB for very simple functionality.
+ CPU usage (not noticeable) and memory (46 MB) appear to be under control by recent OS X standards (not very high grant you).
