  There is an automatic system that extracts translations from desktop files (and alike), and injects translations back.

I did this by turning the background in the field red if it wasn't valid and returning it to default when it became valid. Is there a "KDE way" to do something like this or should I just leave everything with the default background and not give the user any immediate feedback that there is a problem?
  
  I mentioned it one point below:
  
  >> - a better option to validate an input in a line edit is to use the embedded validator options, see `QLineEdit::setInputMask` and `QValidator`
  
  IOW, instead of validating the input //after// the user inputs it, do it //before//.

  IMHO having 0 as value for that is good; otherwise, a proper QIntValidator for the line edit restricts the input the user can insert, removing the need to do the validation manually.

  `wireguardwidget.h`, for example.
  
  I am not familiar with how Q_DECL_OVERRIDE is used but I did look at how all the other VPN implementations did it and it looks like they use the exact same mix of `virtual` & `Q_DECL_OVERRIDE` as I used in WireGuard.
  
  See commit 111ac65ae79f1a777e3b4a6389e916f0dfccd35e <https://phabricator.kde.org/R116:111ac65ae79f1a777e3b4a6389e916f0dfccd35e>.  It looks like you are developing against an old version of plasma-nm, or not on master anyway.

What I was trying to do was to highlight the text in a couple of labels by making them a little bigger than the default font and making them bold. Is there a "KDE way" to highlight something like this? Maybe a way to say "this is a header" or similar?
  
  Rather than "how can I make some text bigger", the question is "what do you need to do". Since you are grouping widgets, then use a QGroupBox.
  
  Oh, and that adds another thing to fix: `wireguard.ui` really needs a top-level layout, instead of hardcoding the size of the widgets...

  This was added by dbb4e2d5d47a6546014d433a1533d4ef4cfb7137 <https://phabricator.kde.org/R116:dbb4e2d5d47a6546014d433a1533d4ef4cfb7137>. Weird choice, I guess this can be left as it is.
