About Tk.getOpenFile and getSaveFile:

> * Favorite dirs and files
> * Recent dirs and files

For dir, :initialdir option may be useful.
# And sometimes, :initialfile option may help you.

> * Using filters (regexp would be nice)

:filetypes option can control listed files in the dialog.
Extension-style or glob-style of file patterns are available 
on its description.
Please read the Tcl/Tk's manual about tk_getOpenFile.
You can give a Ruby's array for a Tcl's list.
e.g.
Tcl's list
------------------------------------------
  {
    {{Text Files}       {.txt}        }
    {{TCL Scripts}      {.tcl}        }
    {{C Source Files}   {.c}      TEXT}
    {{GIF Files}        {.gif}        }
    {{GIF Files}        {}        GIFF}
    {{All Files}        *             }
  }
------------------------------------------
==>
Ruby's array
------------------------------------------
  [
    ["Text Files",     [".txt"]        ],
    ["TCL Scripts",    [".tcl"]        ],
    ["C Source Files", [".c"],   "TEXT"],
    ["GIF Files",      [".gif"]        ],
    ["GIF Files",      [],       "GIFF"],
    ["All Files",      ["*"],          ]
  ]
------------------------------------------

> * Having incremental search (i.e., limiting the displayed files/dirs
> while typing into a search field)

"File name" field of Tk.getOpenFile, getSaveFile 
accepts a glob pattern for filtering listed files.
Incremental search is not available. 
But on Tk8.5, <Tab> completion is available.

> * Pasting and copying file path from/to clipboard

e.g.
------------------------------------------
TkClipboard.append(Tk.getOpenFile)

f = TkClipboard.get
Tk.getOpenFile(:initialdir=>File.dirname(f),:initialfile=>File.basename(f))
------------------------------------------

> * Fast

Use a faster machine. ;-)

> Nice to have:
> * Font color dependent on File extension.

You must write a script (or a class).
Please check the usage of TkWindow#grab, TkWindow#grab_release, 
and TkVariable#wait or TkWindow#wait_destroy.
