When working with a big piece of text, I sometimes scroll down and copy some text into another tab. When switching back to the first tab, both the input and the output pane is back on top. So I don't know where I was working just now.

Describe the solution you'd like

If you have a partial command line like --option1 value1 --option2 value2 --options3 value3 and you copy and paste it to a response file, and then break it up to a line per token so that the response file works, if you are not careful enough you can leave trailing spaces behind like this:

--option1<space>
value1<space>
--option2<space>
value2<space>
--options3<space>
value3

Everything in diagrams.css should be scoped to some wrapping css class, because as is it cannot be bundled with the rest of an app's css because of styles like this:

div {
    -webkit-touch-callout: none;
    -webkit-user-select: none;
    -khtml-user-select: none;
    -moz-user-select: none;
    -ms-user-select: none;
    user-select: none;
}

svg {
    width: 100%;
}

       rdate      = "RDATE" rdtparam ":" rdtval *("," rdtval) CRLF

       rdtparam   = *(
                  ;
                  ; T
