Burp Suite does not create a [dot]app folder, so every time I want to start it I have to open the Terminal and run "java -jar /path/to/burpsuite.jar", which is not a big problem but I very much prefer to press Cmd+Space, quickly type "burp" and then press the Return key to start the Platypus wrapper.
I have both community and professional editions installed (trial expired), and would always open via spotlight or the dock shortcut... not sure what's going on with the parent comment's application.
Platypus allows you to create a Mac [dot]app wrapper around any type of scripts.
