How to Install the Collector GNOME Shell Extension

Updated

To install the Collector GNOME Shell extension, go to mijorus.it and use the "Install Collector GNOME Extension" link on the site. The site describes this extension as the complementary GNOME Shell extension for Collector, the app whose tagline is "Drag and Drop to the next level." The site does not publish a version number, a GNOME Shell version range, or a list of extension features, so treat the site link as the entry point and confirm compatibility in GNOME before relying on it.

What the site provides

The homepage of Lorenzo Paderi's personal site (mijorus.it) lists Collector among his software projects and presents the GNOME extension as a companion piece to the main app:

Item on the site What it tells you
"Collector — Drag and Drop to the next level" Collector is the main application
"Install Collector GNOME Extension" A dedicated install entry for the GNOME Shell extension
"Install the complementary GNOME Shell extension" The extension supplements Collector under GNOME

The site also links a separate tutorial, "How to configure Collector on KDE," which covers keeping Collector windows always on top in Plasma. That is KDE-specific guidance; it is not part of the GNOME extension install.

Install steps

  1. Open mijorus.it in a browser.
  2. Find the Collector section and select the "Install Collector GNOME Extension" link. This is the install entry the site provides for the extension.
  3. Follow the page the link opens to complete the installation in your GNOME environment.
  4. Verify the result: open the Extensions app (or run gnome-extensions list in a terminal) and check that the Collector extension appears and is enabled.
  5. Test it against the main app: launch Collector and try a drag-and-drop action to confirm the extension is active.

The site does not spell out the exact mechanism behind the install link, so the expected result at step 3 is simply that the extension becomes available to GNOME Shell. If the link leads to a browser integration prompt, accept it and confirm the install when GNOME asks.

Common snags

  • Extension not listed after install: GNOME Shell may need a restart (log out and back in on Wayland) before a newly installed extension shows up.
  • Install link does nothing: browser integration for GNOME extensions may be missing or disabled; enable it and retry the link from mijorus.it.
  • Version mismatch: the site gives no supported GNOME Shell versions, so if GNOME flags the extension as incompatible, check the extension's own page for its version support rather than assuming the site link covers your release.
  • Confusing it with the KDE guide: the "always on top" configuration article on the site is for KDE Plasma. Do not follow it as GNOME install instructions.

Related projects on the same site

If you arrived at mijorus.it while setting up Collector, the same page also points to other tools by the same developer: Gear Lever (installing AppImages), Simba (a Samba manager), Smile (an emoji picker for Linux), and Whisper (listening to your microphone via PipeWire). These are separate projects with their own entries; none of them is required to install the Collector GNOME extension.
