Finder Open iTerm Here: Drop a folder on this script (or just run it) to open a new iTerm window there. If the selected item isn't a folder, it will open the item's parent folder. Great when bound to a hotkey in FastScripts or added to the Finder Sidebar. Works with iTerm2-v3 (2.9)

It's a great gist, thank you. Another question, how to save it as an app, and put it in XtraFinder's toolbar like this ?

When you open up Automator, you want to select "Application." Then, just save it and it should be saved as a ".app"

To change the icon, see "Changing an item's icon" at https://support.apple.com/en-us/HT201737

Once you've changed it, hold down "command" and then drag it into the toolbar. (I know this works for the built in toolbar. Not sure about XtraFinder but it's worth a shot.)
