LTSpice is a Windows application, but I've never had any trouble using it under WINE. It is proprietary, but the free version suffices for many problems.

 Hi Rod,

Well, this is not a front end for the Spice that you have. (Spice is good,
and very useful, but it's not so much 'drag and drop' as it feels like
you're asking for.)

When I was in school, I was told of this simulator by a classmate, and it
was a wonderful thing to get a sense of what is actually going on. At the
time it was a Java-only version, but I see that now they also have a
javascript version. At the very least, you can download the Java files and
run them locally.

Anyway, check it out here: http://www.falstad.com/circuit/

There are very similar apps (as far as ease of use and visual feedback) for
both iOS and Android. I have purchased the paid version of a few, and if
you're interested in those I can go digging and see what they are. I only
really use them when we're on vacation and I have an idea I want to check
out, so I haven't used them in a while. Not as powerful or easy to use as
desktop programs, but of course very portable.

Thanks,
Erik
