Single column, app responsiveness fixes checklist

[WatchMkr]

General

• Set minimum width to 280 px 360 px (the standard we've now set for COSMIC apps. We'll need to check again with this narrower size)
• Always collapse to the content. On first launch the app collapses to the NavBar. If I change the page in the NavBar, it seems to collapse to the content.

Desktop and Panel > Panel

• Wrap "Gap between panel and screen edges" so the toggle doesn't move
• Size: wrap the slider to a second line
• Background opacity: wrap the slider to a second line
• Adding an applet isn't responsive but should be fixed on this issue.

Desktop and Panel > Dock

• Wrap "Gap between dock and screen edges" so the toggle doesn't move
• Size: wrap the slider to a second line
• Background opacity: wrap the slider to a second line
• Adding an applet isn't responsive but should be fixed on this issue.

Input Devices > Mouse

• "Primary button" Left|Right segmented button doesn't shrink well. Reducing the size of the label container seems because there's enough room. Alternatively, we can wrap the button to the second line.
• Mouse speed: wrap the slider to the second line
• Scrolling speed: wrap the slider to the second line

Input Devices > Touchpad

• "Primary button" Left|Right segmented button doesn't shrink well. Reducing the size of the label container seems because there's enough room. Alternatively, we can wrap the button to the second line.
• Touchpad speed: wrap the slider to the second line
• Scrolling speed: wrap the slider to the second line

System & Accounts > About

• Device name entry should probably wrap to the second line.
  The hardware section has odd wrapping but it's not a high priority. We can come back to it in a later release.
