Older windows tended to have a 2" (or greater) trim around them. That 2" trim was referred to as the "brickmould" trim. Newer windows normally don't have brickmould (because they have an installation flange instead), so the edge of the window only looks like it's about 3/4" to 1" wide; it looks rather skimpy compared to old windows. That's one of the main reasons why new homes will put a 3-1/2" or wider trim around the window; it gives it some dimension, some visual punch, and looks good.

Shutters are still used on new homes to achieve a certain older look, but it's not as common as it used to be.

As for your question about Silverline, it tends to be a lower end vinyl window, what some would call a "builder grade" window. Nothing wrong with that, they have their place for those who can't afford the best of everything. Most of their sales I believe are though builders rather than remodelers. I don't have a problem with that, as long as the home is more akin to a starter home and not a $500k custom home.

Other trends these days include larger glass areas (because the glass is so much more energy efficient than years ago), and therefore brighter rooms. Transoms (windows above windows) are popular for the same reasons, as are taller ceiling heights to accomodate the transoms.
