1. iCalc: That's not a spreadsheet application like Excel. One wonders why you didn't use Excel or Numbers.
2. Agreed, and that's the fault of Intuit who, hold your breath, claim that they are going to bring back Quicken for the Mac. Totally rebuilt and equal to the Windows version. In the mean time, you could have been running Quicken for Windows on your Mac, using VM software. Windows runs on a Mac!

4. Drag the App to the trash. Yes, got to admit, that's really difficult.
5. Finder will show you everything you want. I wonder if you mean something else. Do you mean the "Find" command? Selecting a file that has been found using the "Find" command will display the location of the file.
To show the date in Finder, just view "As List" (Same as Windows)
