I see it wasn't mentioned here previously, but looking at src/core/gui/mainwindow.ui in Qt Designer, I see the button has a green checkmark for "Download & Install". Four issues with this:

• Capitalization;
  
• The checkmark is inconsistent with another example of a red "Download" button found previously somewhere, or a standard button which looks like a green arrow pointing sideways saying "Update" (in the new IP2C window);
  
• This also has a warning triangle next to it, although it's not arguably a warning where such warning triangle is normally used (e.g. "This path doesn't exist.");
  
• Ending the "New updates are available:" and "Updates have been downloaded:" to colon punctuation may be inconsistent (e.g. compared to IP2C update dialogs).
