Ergonomics

[Drumor]

I got those propositions to enhance the user interface:

• Channels : Get a "my channels" tab to find user's channels easier.
• Channels - User Permissions : Put contrib,admins,... on the top of the list.
• Channels - Buttons : "Configure" -> "Settings" and "Application"->"Edit"
• Channels - Subscriptions: Get the previous window while clicking on back.Nowadays, you have to do the search again.
• Channels - Details : Get the previous window while clicking on back.Nowadays, you have to do the search again.
  -Channels - Preview : Get the previous window while clicking on back.Nowadays, you have to do the search again.
• Channels - Configure : Get the previous window while clicking on back.Nowadays, you have to do the search again.
• Editor plugin : Replace "Edit" -> "Settings", "Open" -> "Edit".
• Editor plugin : When editing a slide, the selected template and made layout is lost. (It's more a bug than an enhancement)
• Screens : Change "Configure" -> "Settings"
• Screens : Put the subscribed screens on the top of the list.
