The icons that appear on the opening screen under videos, pictures, programs, etc. was set-up to satisfy most of the users. However, as you know, if you click on addons under videos, you have access to much more addons. May be you prefer to have one of these as the first icon under videos.
The video below will show how to add icons if they are not there. You can also use it to change any icon listed. Just click on the addon you want to change, then choose the new addon from the list of addons that will appear.
The following content is from this site.
Step 1 – Hover or Click on System and then click on Settings.
Step 2 – Click on Appearance
Step 3 – Navigate to the Skin Tab and move to right to the Skin Settings Tab (Pictured)
Step 4 – Navigate to the Add-on Shorcuts section and press right or move your cursor right and click on Add-on 1 (You can click on any of the Corresponding Add-on 1-7. Just remember that Add-on 1 will be the first shortcut on the left of your screen.) If you scroll down further you will see Music and Program Add-on Shortcuts.
Step 5 – after pressing Add-on 1 a pop up with all of your video addons will appear.
Step 6 – Choose the addon you want to create the shortcut for. (In this example I chose the CBS News Addon)
Step 7 – The addon you selected will now be shown on your homescreen under the Video section. Please repeat step 5 & 6 for any other short cut spots you want to add or change.
Step 8 – Press the Home Icon at the bottom right of the screen and move to the Video section. You will now see the addons that you have selected as short cuts on the main screen.
That is it folks. You have no mastered how to add, or change shortcuts in Kodi XMBC.
Hope that helps.
