I currently use Linux as my primary desktop OS, and have done for more years than I care to remember. In recent years I've settled on GNOME and XFCE as my environments of choice.
For a number of reasons (pressure to use AD-based resources, better availability of supported software, etc) I am contemplating a switch to Windows 7 as my primary OS, but there are a few parts of my Unix-like environment I'd struggle to move away from after all these years, mostly related to mouse behaviour. What I want to know is -- can I make Windows 7 give me these same behaviours, and make the migration more comfortable?
focus follows mouse -- I move my mouse cursor into a window, it gets focus until I move the mouse into another one. I click, it comes to the front. I start typing, the cursor hides. This makes me very happy -- I could live with the window losing focus when the mouse leaves (rather than when it enters another), i.e. without sloppy focus, but FFM is just how my brain works now.
select to copy, middle click paste -- having to use menus or keyboard shortcuts to copy and paste is probably the single most antagonising thing for me when temporarily using a Windows machine. I buy laptops with middle mouse buttons above the trackpad (for use with a trackpoint), for this exact purpose, although the mouse scrollwheel works too. Can Windows be made to support this? Some applications get close (PuTTY has select to copy, right click to paste, IIRC) but scroll-click's behaviour seems to vary across applications.
I've no great hate for modern Windows, I switched away in the earlyish XP days (before SP2) and use it often enough to support 40ish colleagues who use XP or 7 on their desktops all day long, but I find these UI issues just annoying enough to slow me down when e.g. coding. Frustrating, when I mostly want to switch OS to get access to better selection of programmer's editors and IDEs!
