Alright, let's tackle your three questions one by one for Ubuntu 16.04 LTS:

1. Stop the top Panel from showing active browser tab content or hide the panel

Unity's global menu is the culprit here, and you have a few ways to fix this:

Disable browser tab previews in the global menu
For Chrome/Chromium:
- Open Chrome and navigate to chrome://flags/#enable-unity-native-menus
- Set the option to Disabled, then restart Chrome. This stops the browser from pushing tab titles to the top panel.
  For Firefox:
- Type about:config in the address bar, accept the warning prompt.
- Search for ui.use_unity_global_menu and set its value to false, then restart Firefox.
Globally disable Unity's integrated menus
If you want all apps to keep their menus inside their own windows instead of the top panel, run this terminal command:
```
gsettings set com.canonical.Unity integrated-menus false
```
Log out and back in for changes to take full effect.
Hide the top Panel entirely or auto-hide it
Option 1: Use Unity Tweak Tool
- First install it via terminal:
```
sudo apt update && sudo apt install unity-tweak-tool
```
- Open Unity Tweak Tool, navigate to Panel settings, then choose Auto-hide (panel hides when not hovered) or adjust settings to hide it permanently.
  Option 2: Command line shortcuts
- Enable auto-hide:
```
gsettings set org.compiz.unityshell:/org/compiz/profiles/unity/plugins/unityshell/ panel-autohide true
```
- Make the panel fully transparent (effectively hidden):
```
gsettings set org.compiz.unityshell:/org/compiz/profiles/unity/plugins/unityshell/ panel-opacity 0
```

2. Add the top-right circled icon to the taskbar (Unity Launcher)

How to do this depends on the app, but here are your options:

Check for a built-in "Add to Launcher" option
Right-click directly on the green-circled icon. If you see an option like "Add to Launcher", click it—you're done!
Manual desktop file creation (if no built-in option exists)
1. Find the app's executable path:
  Open a terminal and run which <app-name> (replace <app-name> with the program's actual name, e.g., gimp). Note down the path it returns.
2. Create a custom desktop file:
  Run this command to open a text editor for the new file:
```
nano ~/.local/share/applications/custom-app.desktop
```
  Paste this template, replacing placeholders with your app's details:
```
[Desktop Entry]
Name=Your App Name
Comment=Short description of the app
Exec=/path/to/your/app/executable
Icon=/path/to/app/icon.png
Terminal=false
Type=Application
Categories=Utility; # Adjust category as needed (e.g., Internet; Graphics;)
```
  Save and exit nano (Ctrl+O, press Enter, then Ctrl+X).
3. Make the file executable:
```
chmod +x ~/.local/share/applications/custom-app.desktop
```
4. Add to Launcher:
  Open the Dash (press the Super key), search for your app's name, then drag its icon to the Unity Launcher on the left side of the screen.

3. Alternative desktop environments without this issue

Unity's global menu behavior is unique to it, so switching to another desktop will eliminate this problem entirely. Here are solid options for Ubuntu 16.04 LTS:

GNOME Shell: The default desktop for newer Ubuntu versions—clean, modern, and free of Unity's global menu quirks. Install it with:
```
sudo apt update && sudo apt install ubuntu-gnome-desktop
```
KDE Plasma: Highly customizable, great if you want full control over your desktop layout. Install with:
```
sudo apt update && sudo apt install kubuntu-desktop
```
Xfce: Lightweight and fast, perfect for older hardware or users who prefer a minimal setup. Install with:
```
sudo apt update && sudo apt install xubuntu-desktop
```
MATE: A continuation of the classic GNOME 2 desktop—familiar, stable, and free of Unity's specific behaviors. Install with:
```
sudo apt update && sudo apt install ubuntu-mate-desktop
```

After installing, log out, then click the gear icon next to the login button to select your new desktop environment before logging back in.
