Earns its place in the superhive library for a narrow, practical job: turning any Blender editor into a standalone window from a menu selection or a hotkey.
Blender Multi-Window Tool is an add-on that opens Blender editors in their own popup windows. Rather than working through View ‣ Area ‣ Duplicate Area into new Window, you pick an editor and it opens in a fresh window in one click. You can also assign hotkeys to open a window quickly, and the latest version lets you choose the window size.
A wide range of editors can be opened this way, including the 3D Viewport, Asset Browser, Camera Preview, Dope Sheet, File Browser, Geometry Node Editor, Graph Editor, Image Editor, Shader Editor, Outliner, Timeline, UV Editor, Text Editor, Spreadsheet and Video Sequencer, among others.
The add-on is compatible with Windows and Linux, and Blender 3.0 or newer is recommended. It installs from Preferences by loading the add-on zip, then runs from the Topbar under Window ‣ Layouts. It's released under the GPL license and covers Blender versions from 2.8 through 4.3.
Blender Multi-Window Tool is best for blender users who want individual editors in separate popup windows without manually rearranging their workspace layout.
Blender Multi-Window Tool is completely free to download and use.
Blender Multi-Window Tool lists compatibility with Blender versions from 2.8 up through 4.3, including the 3.x releases and the 4.0 to 4.3 line. The developer recommends Blender 3.0 or newer for the add-on. If you're on 4.3, it falls within the supported range, so opening editors in popup windows should work as described. For older files, the listing also covers versions down to 2.8, though the recommendation to stay on 3.0 or above is worth keeping in mind.
Blender Multi-Window Tool is compatible with Windows and Linux. macOS isn't listed among the supported platforms, so if you're on a Mac it's best to check with the developer before relying on it. On Windows and Linux you can open Blender editors as separate popup windows, assign hotkeys to them, and set the window size, all from inside Blender. Confirm your platform matches the supported list before installing to avoid surprises later.
Blender Multi-Window Tool installs through Blender's add-on system. Open Preferences, go to the Add-on section, choose Install, and select the multiwindow_tool zip file. Once it's enabled, you use it from the Topbar: open the Window menu, then Layouts, and select the editor you want to pop up into a new window. You can also assign hotkeys so a window opens with a keypress. The whole flow stays within Blender's standard preferences and menus.
Blender Multi-Window Tool can open a wide list of editors as popup windows. These include the 3D Viewport, Asset Browser, Camera Preview, Dope Sheet, File Browser, Geometry Node Editor, Graph Editor, Image Editor, Movie Clip Editor, Nonlinear Animation, Outliner, Preferences, Properties, Shader Editor, Texture Node Editor, Timeline, UV Editor, Console, Text Editor, Info, Spreadsheet and Video Sequencer. Each opens in its own window from the Window ‣ Layouts menu, and you can set the size of the window as it opens.
Blender Multi-Window Tool is listed as free in this catalog. Licensing and pricing can change over time, so check the developer's page for the current terms before you download. The add-on is released under the GPL license, which is common for Blender add-ons and applies to what you can do with the code itself, separate from how the tool is distributed here. When in doubt, the developer's page is the place to confirm the latest details.
