I used a lot more than five back in the day. Honestly I think that number ranged in the dozens.

These days I think I use a lot fewer than that thanks to OS3.9 + BB1-4. Although the argument could be made that the Boing Bags are nothing more than a collection of patches, too.

Here's a few to add to your list off my A2000, however:
- PFS file system
- Updated libraries thanks to Cosmos, Peter K., THOR, etc. (exec, intuition, graphics, layers, math, icons, etc.)
- TLSFMem
- Visual Prefs (had to remove Birdie since it crashed with the updated libs)
- Env-Handler
- FPPrefs and the Rebel palette (if not using high-color screen modes, see mfilos's great blog entry on setting this up)
- Freewheel and the Cocolino driver with modern mice
- Multi_CX
- DirWork
- MagicMenu
- WHDLoad
Honestly I'm surprised I don't have more, those updated libraries really made a lot of other things unnecessary. I should start looking into how to burn my own ROM's, lol.

Also one other tip that maybe some folks don't know about, even if you have 3.9 + all four of the Boing Bags there are still updates out there. Just put the name of every program into the Aminet search and you'll find that a few have been updated beyond what was distributed at the time. Just my .02 cents. Have fun, many patches can make for a frustrating, unstable experience. Or a great one! :lol:
