Please see:

1. Theme.
   Is it possible for me to omit the Theme option from the window? Not all themes are displaying good in my support forum and if possible I would like to lock down the theme that anyone uses to Atomic.

2. Linennumber offset
   There are two issues here:

• It has a typo error because it should be Line number offset or maybe Start with line number.
• It makes sense that this control comes before the Point out Lines control.

3. Show Linennumbers
   This has a typo. It should really be Show Line numbers.

4. Point out Lines
   I wonder if it is better to phrase this option as "Lines to highlight".

To me, I reckon:

• Display line numbers
• Begin with line number
• Lines to highlight

It is obviously entirely your decision but there are two typos and it makes sense to swap the two controls around I think.
