​1. After switch to secondary view (Forms designer, WPF designer,
HexEditor, XmlEditor) with keyboard (Ctrl + PgUp/PgDown) there is no way
to activate content without mouse;

​2. Additionally to point 2 if I override InitiallyFocusedControl
property in my secondary view and set focus to content form (WinForms)
then I has keyboard focus on this form (e.g. I can use arrows for
navigation in content etc.) but icons on ToolBar (copy, paste, undo and
etc.) inactive until I has mouse click to this form;

​3. Switching via Ctlr + Tab to file which opened in secondary view
doesn’t set focus to it content even content has focused before
switching.

Putting this on the plate for SD5 beta 2 as it sounds like an annoying bug we should be able to fix. Or maybe already have fixed (I didn't try reproducing it).

As far as I was able to debug the problem, partially, it seems to be a problem with AvalonWorkbenchWindow.SetFocus et al. because these methods expect an IInputElement. The cast ActiveViewContent.InitiallyFocusedControl as IInputElement fails for non-WPF view contents.

My proposal would be to add a void SetFocus() method to IViewContent instead of object InitiallyFocusedControl { get; }.
