OT: @PeterX: Second Life is evil in the way big cities are; you can find
absolutely everything there if you know where to look. It's addictive largely because it is in some ways much more empowering and fascinating than real life, the visuals are often bright and cheering, and it's so easy to access. It's also addictive because porn is addictive and it's not at all hard to find it -- sometimes you'll see things you don't want to in the welcome centers.
Not so OT: If you want to try the pie menu with fewer problems, try
Digiworldz or
Discovery Grid; their welcome centers are clean. The
Firestorm viewer (client) has the pie menu; I'm not sure which others do. Most of the pie menu entries work as well as ever, but jumping in and out of edit mode (which was extremely useful) has been broken for no reason for over 10 years. Terrible software which contains a few left-over bits of genius. Companies like Digiworldz and Discovery Grid are trying to make something nice out of it with compatible server software (OpenSim), but it's too big a task for a small company.
@PeterX again: I set Win98 to single-click everywhere.
You could do that with Active Directories. I don't think you can do it in Win10. In Linux, I preferred the command line with menus for lesser-used programs.
@bloodline: I've configured raising windows in so many different ways over the years.
I always had mouse-focus; it makes so much more sense at the window level than click-to-focus. Some window managers in mouse-focus mode defaulted to not raising the window unless the title bar was clicked. That was almost okay, but the taskbar could be a fiddly little thing. I often had window managers configured with keybindings to raise and lower windows, and generally found lowering a more useful operation than raising. Lowering can also replace alt-tab. The only time I thought raising better than lowering was when I had a mess of little windows and one or two big ones.
