Launcher
Summon it, drop it in.
Summon a small input window with a shortcut and ask Blaze on the spot. Drop a file and it runs right away.
What the Launcher does
Instant shortcut launch
Use a shortcut like double-tapping Control to summon the input window from any screen.
Drop shelf
Drag a file onto the area near the tray and it launches with the file attached.
Runs in the background
Stays resident even when the main window is closed — summon it from startup.
Auto-run with a default Skill
Set a default Skill and just dropping a file runs it automatically.
