I've changed some of positioning for the multitasking landscape view which aligns things better, here's what i changed in meegotouchhome.css
line 392-408
MAbstractLayoutPolicyStyle#SwitcherOverviewPolicy. Landscape {
margin-left: 4.5mm;
margin-right: 4.5mm;
margin-top: 0mm;
margin-bottom: 2.0mm;
vertical-spacing: 1.9mm;
horizontal-spacing: 1.9mm;
}

MAbstractLayoutPolicyStyle#SwitcherDetailviewPolic y.Landscape {
margin-left: 4.5mm;
margin-right: 4.5mm;
margin-top: 0mm;
margin-bottom: 1.4mm;
vertical-spacing: 2.0mm;
horizontal-spacing: 2.0mm;
}
Line 460-472SwipeSwitcherButtonStyle#SwipeOverviewButton.La ndscape {
minimum-size: 23.5mm 13.8mm;
preferred-size: 23.5mm 13.8mm;
maximum-size: 23.5mm 13.8mm;
icon-size: 23.5mm 13.8mm;
}

SwipeSwitcherButtonStyle#SwipeDetailviewButton.Lan dscape {
minimum-size: 36.8mm 21.6mm;
preferred-size: 36.8mm 21.6mm;
maximum-size: 36.8mm 21.6mm;
icon-size: 36.8mm 21.6mm;
}

Line 491 and 512 i have made specific to portrait by adding .portrait
I then added the following landscape equivalents

SwipeCloseButtonStyle#SwipeOverviewButtonCloseButt on.Landscape {
icon-id: "icon-m-framework-close-thumbnail";

margin-top: 10.0mm;
margin-right: 9.3mm;

/* Extended button size: 64x64 (size + extensions) */
minimum-size: 4.8mm 4.8mm;
preferred-size: 4.8mm 4.8mm;
maximum-size: 4.8mm 4.8mm;
icon-size: 4.8mm 4.8mm;

/* Reactive margins, with negative margins compensated */
reactive-margin-left: 0.8mm;
reactive-margin-right: -7.3mm;
reactive-margin-top: -9mm;
reactive-margin-bottom: 0.8mm;

release-feedback: priority2_close;
}

SwipeCloseButtonStyle#SwipeDetailviewButtonCloseBu tton.Landscape {
icon-id: "icon-m-framework-close-thumbnail";
margin-top: 18.0mm;
margin-right: 15.4mm;


/* Extended button size: 64x64 (size + extensions) */
minimum-size: 4.8mm 4.8mm;
preferred-size: 4.8mm 4.8mm;
maximum-size: 4.8mm 4.8mm;
icon-size: 5mm 5mm;

/* Reactive margins, with negative margins compensated */
reactive-margin-left: 0.8mm;
reactive-margin-right: -13.0mm;
reactive-margin-top: -17.0mm;
reactive-margin-bottom: 0.8mm;
release-feedback: priority2_close;
}
