Are there any app's that you can recommend for adding some application launchers to the workbench menu or similar?
I already have a dock for the most used stuff, but it'd be nice to have an alternative.
AmiStart like already mentioned must be the best Windows-like startprogram. Depending on your AOS version you can use good old TooldDaemon to add programs to menues. There was a replacement or two released for later versions of AOS but I can't remember the name.
