Select several tabs in the tab strip, then right-click and choose a Space (or "Add to New Space") to add them all at once function fixed.

Spaces are now easier to organize and name:
• Drag the Space tabs to reorder them.
• Right-click a Space to rename it, change its color, or create a new Space.
• Creating a Space now drops you straight into naming it, with the default name selected so you can type right over it.
• A Save button appears beside the Space name only when you actually change it, so there is no clutter.
• Right-clicking a link and choosing "Add to New Space" now lets you name the new Space on the spot.
• Fixed: naming a Space something that starts with a number (like "3D Printing") no longer switches you to a different Space.
