What is the enhancement in mind? How should it look and feel?

I was wondering if you'd be able to add some generic filtering into the Inventory Pane.  Some buttons on the right side for Gear Quality and Gear Type would be a very nice addition.  I've seen in it other addons and was hoping you might be able to include the same here.

Functionality:
1.  Two+ tab like buttons that extend past the right side of the Inventory screen.
  1.a.  One button that is identified as "Quality"
  1.b.  One button that is identified as "Type"
2.  Button "Quality" to have a right click feature which will filter all inventory items to a specific type of Quality.  Normal, Common, Rare, Epic (any others I may have missed).  
  2.a.  Can check only one.
  2.b.  Can check many.
  2.c.  Upon opening Inventory Window, all checked filters are reset to a default as to not hide items.
  2.d.  Options screen to have a "Save last filter" option to skip resetting to defaults unless the game has recently been started.
  2.e.  Right click menu to have two extra options beyond standard "Quality" types.
    2.e.I  "Reset Filters"
3.  Button "Type" to have a right click feature which will filter all inventory items to a specific type of gear.  Trade Skill, Quest Items, Food & Water, etc.. (any others I may have missed).
  3.a.  Can check only one.
  3.b.  Can check many.
  3.c.  Upon opening Inventory Window, all checked filters are reset to a default as to not hide items.
  3.d.  Options screen to have a "Save last filter" option to skip resetting to defaults unless the game has recently been started.
  3.e.  Right click menu to have two extra options beyond standard "Types".
    3.e.I  "Reset Filters"

Please provide any additional information below.

Hope above was enough. =)  thanks!
