Description:
Suggesting to add a GUI based setting that would allow LibreOffice splash screen to be turned off and also open LibreOffice applications smoothly after this splash screen setting is set to be off.

Actual Results:
LibreOffice by default shows a splash screen every time any applications within the suite are opened, for example Calc and Writer.
I have seen that there is a way to hide this splash screen if desired, by editing the following file
`/etc/libreoffice/sofficerc`

This does work, but when applied, any time you open a Calc or Writer based document, for example from your file manager, it causes a flashing effect of windows.
file manager / libreoffice window / file manager / libreoffice window which then loads up Calc or Writer.
Not sure if other users experience this?
Not sure if this is the purpose of the splash screen?
This can be visually distracting and is not desired.


Expected Results:
Suggesting two things
-Using current `/etc/libreoffice/sofficerc` approach mentioned above
If it is possible, allow the splash screen to be hidden, but then fix this so that file manager just shows after hitting ENTER to open the file, and then just have LibreOffice window to show when the document is loaded, which is how applications generally function.

-GUI based setting
If the above is not possible, then this second suggestion does not really mean anything because it would be probably better for user to keep splash screen rather then see flashing windows.
However if this could be achieve, then I am suggesting to also add a graphical setting in 
`Options - LibreOffice` section for user to show/hide this splash screen, rather then requiring user to sudo into a system based file to turn this splash screen on/off, which most users also would probably not know about.
