[yw4z]

KNOWN ISSUE

• Minor: Hover effects not working properly for first button if its loaded from cache and not refreshed
----ex: Open create presets dialog > Choose printer > Press Create > Press Return > hover effect not works for Create > Press Create again > Hover effects not working for Return button
----No automized solution yet

FIXES

• buttons doesnt get focus. switched to wxPanel instead wxWindow
• Primary button stealing focus from inputs / combo boxes. limited SetFocus function, now its focuses only if there is no focus. This will also fix cant write number / text to input boxes on some dialogs
• No left gap on small windows
• Back button translation on create printer / filament dialog. Problem with this one "Back" used as side of object on translations. added GetRETURN() for quick access and fixed proper case usage in #9831
• First button not getting hover effects. Used ->Raise() to ensure every button has correct Z-order

CHANGES

• Switched to wxPanel instead wxWindow. wxPanel also supports keyboard shortcuts when they defined in class. its not required to bind events on parent
