At work, I use iTerm2 as my main terminal emulator. For quick access, I have it configured to drop down from the top of the screen when F12 is pressed.

Unfortunately, it also shows up in the application switcher, bumping up into the 'last used' position whenever it's activated and getting in the way. Since I already have access to the terminal via F12, there's no need for it to be shown in the application switcher as well.

Changing how an application behaves can be done by editing its Info.plist file. The key LSUIElement (according to the Apple documentation) "Specifies whether the app is an agent app, that is, an app that should not appear in the Dock or Force Quit window."

To set this key, open the application's Info.plist at /Applications/[application name].app/Contents/Info.plist and add <key>LSUIElement</key><true/> after the first <dict> tag. The result should look something like this:

1
2
3
4
5
6
7
8

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
    <key>LSUIElement</key><true/>
    <!-- The rest of the plist data -->
</dict>
</plist>

Once the LSUIElement key is set to true, relaunch the application to see the changes.

Be warned that not only does this remove the application from the application switcher, it also removes it from the dock and stops it from showing the menu bar on the top of the screen.

Fehlstart is an application launcher, much like Launchy, Quicksilver, or GNOME Do. However, where other launchers focus on adding features, Fehlstart is as basic as they come. If you want to search for files or control your media player, look elsewhere. Felhstart launches applications. Period.

Fehlstart isn't in any major repositories so it has to be compiled from source.

1. Install dependencies
   • git, gcc, make, libgtk2.0-dev, libkeybinder-dev
   • On most systems these packages will be available through your package manager
2. Get the code
   • git clone https://gitlab.com/fehlstart/fehlstart.git
3. Compile and install
   • Navigate into the folder containing the code
   • Run make
   • Run make install (with the needed permissions)
4. Add fehlstart to your window manager's autostart list
5. Log out and back in to launch Fehlstart.
6. Press the key combination <Super> + <Space> to bring up the launcher
7. Type to search through the installed applications, then press <Enter> to launch.

Gmvault is an open source project that allows users to download all of their emails, as well as the labels.

From there it's as simple as opening them up in a program like Outlook or Thunderbird to view them. It also includes an option to restore the emails.

Most email clients have the capability of doing this, but this was by far the quickest way. Automatic incremental backups can also be done by running a 'quick sync' regularly.
