Description:
When using Recent Documents selection in file pulldown menu, as default please only show files with three letter extensions appropriate to the app - e.g. *.doc or *.txt for LibreOffice Word, or *.xls for LibreOffice Calc., etc.  As it is, the selection list is so cluttered it is almost unusable.  There may be occasions where a file has no extension so you can always have an option to show all files. 

Steps to Reproduce:
1. Select Recent Documents under File pulldown
2.
3.

Actual Results:
If you do a lot of work using a mix of Word, Calc, and Draw, you see a long list of files - many or most not relevant to the active application

Expected Results:
See only files relevant to the active application unless I specifically enable list all files


Reproducible: Always


User Profile Reset: No

Additional Info:
List only files relevant to the active application.
