Gnome UI Tweak Tool “Just Perfection” Added Gnome 49 Support

Just Perfection, the popular tool to configure Gnome Shell behavior and UI elements, release new 35.0 version few days ago.

In case you don’t know about it, it’s an extension for GNOME desktop that provides a graphical interface to toggle visibility of the desktop elements, and change the common desktop behavior.

The extension provides pre-defined profiles to one click switch between default, minimal, and super minimal desktop appearance.

While, user may customize by hiding the top-panel, panel in overview, dash (dock), on-screen display (OSD), panel items (e.g., clock, indicators), menu items (e.g., calendar and events in clock menu), items in overview and more.

It as well can adjust the panel size (height), position, padding, clock position, OSD position, alt-tab preview size. And, it allows to disable or change animation speed, choose login to blank desktop or overview, maximize new window, disable Super (window logo) key, and more.

In the past few releases, it keeps adding new features, such as ability to hide quick settings buttons (e.g., Dark Mode, Night Light, Airplane), and use accent color for top panel icons though it requires GNOME 47+ and not work for Ubuntu.

The new Just Perfection version 35 added support for GNOME 49, which is default in Ubuntu 25.10 and Fedora 43, though they are all in development stage at the moment of writing.

And, it added ability to toggle visibility (show or hide) of window menu. It’s the menu that pops-up when you right-clicking on header of an app window, which contains options to take screenshot, set always on top, move, resize, or close window.

There are as well fixes for startup freeze in NixOS, and the page icon issue in preferences window for GNOME Shell 48.

How to Install Just Perfection:

The new Just Perfection releases supports GNOME from version 45 to 49. User may install it by visiting the EGO page via web browser:
