Reapply fit mode on window resize

[char101]

Hi,

Is there any plan to add an option to reapply the fit mode (F9/F10) after the window is resized?

I find that resizing the window and having the zoom level follows is easier than zooming and then resizing the window.

Meanwhile we can implement this feature (on Windows) using an autohotkey script that monitors when the window is resized and send an F10 key to the window:

#SingleInstance force
#NoEnv
#Warn

; Function .....: EWinHook_SetWinEventHook
; Description ..: Sets an event hook function for a range of events.
; Parameters ...: eventMin         - Lowest event constant to handle. Pass the name as a string (eg: "EVENT_MIN").
; ..............: eventMax         - Highest event constant to handle. Pass the name as a string (eg: "EVENT_MAX").
; ..............: hmodWinEventProc - Handle to the DLL containing the hook function at lpfnWinEventProc or NULL.
; ..............: lpfnWinEventProc - Name or pointer to the hook function. Must be a WinEventProc callback function.
; ..............: idProcess        - PID from which the hook will receive events or 0 for all desktop process.
; ..............: idThread         - Thread ID from which the hook will receive events or 0 for all desktop threads.
; ..............: dwflags          - Flag values specifying hook location and events to skip. Specify the value or
; ..............:                    the combination of values as a string. The accepted values are:
; ..............:                    "WINEVENT_INCONTEXT"

; ..............:                    E_UNEXPECTED  = 0x8000FFFF
; ..............: 0                - Parameters or SetWinEventHook error.
; ..............: HWINEVENTHOOK    - Value identifying the event hook instance.
; Remarks ......: Remember to create a WinEventProc callback function to take care of all the messages.
