I created two components: a multi-select combo-box extension which also has search and select all/limit/none capabilities, and a search-box component which the combo uses.
Below is a screenshot of the component. The term 'b' is searched in this case, and since only some items are selected, the select all/none button is marked as "some" (kinda like gmail's email selector).
The components can be found here:

- Ext.ux.form.ExtendedComboBox: https://github.com/deebugger/Ext.ux....tendedComboBox
If you try it, let me know how it went and what's missing / useless / broken.
