We went with 3 things.
1.Slimline, dark metallic look venetians for the kitchen and office,
2. Holland blinds and sheer curtains for lounge, holland blinds and semi sheer for main bedroom, holland blinds with net curtaining for minor bedrooms
3. for the games/family/meals area venetians. This is 2 big sliders and a single window area. all very close together. The verticals provided a cheap , simple solution that works for us. Most of the time the window and one venetian are closed and the other is slightly angled with a small section in front of the open, flywired door pulled back.
I do love those dark plantation shutters though.
