Progress report as we approach 18.04 Beta 2

I have some problems with Ubuntu 18.04 LTS MATE.

Visual group of problems:

  1. I installed human-theme package on it, and it has gray/silver color (#a5a5a2), not standard Ubuntu's orange (#cf8a31). Problem exists since Ubuntu 17.10 and was reported to launchpad as bug 1721955.
  2. Text selection in dialog windows have low contrast.
    Here "A terminal emulator for the MATE desktop" is selected with Ctrl+A, but visually its difficult to determine that it is selected. I did not reported this as bug yet. And here too:
  3. Keyboard LED indicator have low contrast on light themes (see bug 1728715)
  4. mate-welcome has low contrast on Radiant-MATE theme: (it is bug 1762024)

And other problems:

  1. I tried to get fixed the well known bug 1720364 with keyboard layout switching (two layouts, switched by Ctrl+Shift) by creating my own PPA.
  2. Problems with Pluma plugins - see bug 1723259, bug 1743132, bug 1743133, bug 1743134, bug 1743136.

@Wimpy, please ensure than text-styled keyboard layout indicator will have enough contrast (not as in bug 1728711).
