Well, thats nice and all
This reminds me of a famous quote (I wish I knew who it originated from):
"Linux is free, if you do not value your time."
I believe that quote applys here. I create these personal libs because my time is valuable to me. Whatever helps me code faster is a big fat A+ in my book. After all, less time coding = more family time. Of if you have no family, more free time for other things. (like more coding, heh).
freedimension:
The reason for the name "Mini Libs" is just that. It is "mini", not "small". Simple one or two commands that makes coding easier, instead of having to do a 3 - 4 step process in order to get the command in your code, you just type the command (one step).
As for calling them useless, well, I guess that could be called an opinion. For those of us who prefer to save time, would say the opposite. Dispite what you believe, I believe that saving time is a .. well.. time saver.
Conductive to PB, I am going to assume that you mean adding new commands or great new features.. thats well and all, but saving time is also helpful. IF you call this deluting, then you must call all other libraries deluting as well.
Rings:
Would be great if Fred posted here as well. Come to think of it, if you guys agreed on having a prefix for all commands, that would be great. It should be written in the library design docs for the next version of PB or on the PB website somewhere so everybody can know, and change all of the libraries out there for PB to have prefixes

Once that happens, I would gladly concur
No source here though, as mentioned in other threads, that basically takes away the purpose of having libraries. (for me).
