I'm using app-editors/mousepad-0.2.16-r1 on Gentoo Linux. The issue is in that the editor add only opened files to "Open Recent" file list. The newly created text file after saving don't appears in this list. Normally it should appear there. Saved as new (another) file also should appear in "Open Recent" list as a separate item. P.S. Also "Open Recent" "File"-menu item isn't translated. At least in Russian.
Works fine in mousepad 0.3.0.
