Several little touches regarding the in-app interface:
When a file is already picked, show the name of said file under the Pick file button.
Under the Extract to button, show the whole adress to the extraction folder instead of only its name.
Prevent users from tapping the Extract button when an extraction is already underway.
Inform the user that an the app is currently extracting, by replacing the text on the Extract button to "Extracting…" and/or an animated loading icon. Grey the button out as well.
