hi together,

i made some minor fixes about the position of this ux inside the toolbar, to make it work with ext3.0. without these, the item appears on the right end of the toolbar. changes marked red.

original topic:http://extjs.com/forum/showthread.php?t=23615

note: this is not the latest version of the 2.x plugin!

@saki: feel free to implement these changes, if you are porting the latest version to 3.0.


kind regards, tobiu
