GNOME Shell Edge-Flipping is a GNOME Shell extension that provides reactive screen edges to switch between different workspaces, similar to what is provided by Brightside, by some plugin in Compiz or natively in other Desktop Environments like Xfce. Here you can see a video demo.
You can find this extension at the GNOME Shell Extensions website. Using the website is the preferred method since all extensions are reviewed prior to their release and you'll find lots of other cool extensions.
To get the extension directly from my repository, you can use Git to clone it:
git clone git://github.com/Ed-von-Schleck/gnome-shell-edge-flipping.git ~/.local/share/gnome-shell/extensions/edge-flipping@aguslr.github.comIf you don't have Git, you can just download the extension in a tarball and extract it into the appropiate directory:
mkdir ~/.local/share/gnome-shell/extensions/edge-flipping@aguslr.github.com && cd $_
wget https://github.com/Ed-von-Schleck/gnome-shell-edge-flipping/tarball/master -O - | tar -xzv --strip-components 1To customize the behaviour of the extension, just use the configuration button on the GNOME Shell installed extensions website or start the application gnome-shell-extension-prefs and choose Edge Fligpping from the drop-down menu.
By default, once an edge is activated, it will only switch to the adjacent workspace. To switch to the one after that, the edge needs to be reactivated. To change this, set the switch to true.
Also, by default only the top and bottom edges are enabled since workspaces are laid out vertically in GNOME shell and this is less confusing. To disable them, just set the switch to false.
Remember to at least enable either the vertical or the lateral edges, otherwise the extension will have no effect.
To enable lateral edges, just set the switch for horizontal edges to true.
Have in mind that, at the moment, the actions for switching left/right are mapped to up/down, therefore the left and right edges will behave exactly like the top and bottom edges.
There is a delay between activating the edge and switching to the next workspace. This is set to avoid accidentally changing workspace when we were just trying to drag the scroll bar on a maximized window. By default it is set to 300 milliseconds but it can be changed by entering another number or using the spin button.
If continuous flipping is enabled, this parameter also controls the delay between each workspace change. If it's too fast, increase the amount.
There is an offset to prevent the whole extension of the edge from being reactive, again to avoid unintented workspace switching and overlapping other actions (i.e. activating overview or activating the message tray).
By default it is set to 5% of the length of the edge from both ends, that is, only the middle 90% of the edge is used. Again, this can be changed by entering another number or using the spin button.
You can change the size of the edge which is 1 pixel. Also, you can change the opacity so you can a visual reference. Just enter the numbers in the corresponding fields or use the spin buttons.
