I use the trio of ASM, FruitMenu, and WindowShade X; the first is freeware and the latter two are shareware utilities for which I have gladly paid ($13 for the pair). Of course, it should be noted that Apple itself should take care of the interface shortcomings of Mac OS X.
I also renamed Dock.app to NODock.app so that the Dock never launches.
I would like to find a good Trash-on-the-Desktop solution. I have tried Trash X and found it lacking. I currently use keyboard shortcuts for moving items to the Trash and for emptying the Trash. Many times, however, I must open the Terminal to delete items in the Trash due to permissions problems and such, a very un-Macintosh behavior.
I use mostly Carbon applications (AppleWorks, iCab, Eudora, etc.). They seem to have the Mac feel down much better than the Next-ish Cocoa applications. They also generally support Macintosh technologies like metadata and AppleScript *much* better.
I hope that spring-loaded folders return. The rumors are that they will. I also wish that I could organize my entire disk the way I want it to be organized, or at least be able to change the view settings for the entire disk. Currently many things are immutable without resorting to Unix-y bit twiddling, and then many things break because paths and such are hard-coded, another non-Mac behavior. View settings are kept for items in the user's home directory only, again due to permissions problems. Before anyone starts defending file permissions and Unix traditions, please note that I am well versed in Solaris, Linux, HP-UX, etc. I know why things are the way they are (big server iron that is not user-focused) in that world. I also know why things are the way they are in the Macintosh world (user-centered workstations that are generally not shared by many people), and I want that world to stay true to its glorious heritage.
I know that this will not be popular with a certain contingent, but I feel that Thalo usually writes quite accurate summations of Mac OS X's current shortcomings. There is an interesting
Usenet discussion that makes many of Thalo's assertions from a programmer's point of view.
