I did a bit of a search but did not find an answer to this question...
I want to maintain the change of colour of the icon when an item is hovered over but I would like to remove the sliding animation.
Personally, I find this a little distracting, like most animation effects.
Is there a simple way to do this?

did you use a code examiner like FireBug in FireFox to see what ws happening?
it took about 1 minute to examine a menu item, check the styling on hover, find the CSS, shut it off to test and know the answer.

I'll give you a hint, there is a 'transition' CSS rule that is causing the effect. Now you can look thru the virtual CSS files to see if you can find it.

I have just started playing with this theme and as anyone using it would understand, it is in no way simplistic.
Your assumption is that everyone knows how to debug code and determine what is going on and why it is going on. You obviously determined how to resolve this problem and I am a little perplexed as to why you would keep that to yourself. Is that the type of support I should expect if I choose to go with this theme?

Bear in mind, all the members of this forum are volunteers. There's an attitude, which many of the active members support, of encouraging users to learn more, teach a man to code, rather than give him code. In the end, if you can't figure something out, somebody will lead you to the answer. Of course, if you want to hire somebody to give you the answer right away, that option is available, too, with some members (not me, though).

You'll be much more empowered with this or any other WP theme if you know a little. Read this forum and learn.

I am a member of numerous forums and have also been a moderator, so I understand where you are coming from.
That said, I don't know if saying "I found it, see if you can" is the best way forward.
Maybe that is how it is here, but that's not the way I normally respond to users with issues.

My intention was to give you guidance so you can
1) learn more about the theme options
2) learn more about CSS
3) point you to a way you can figure it out

I do not know where anyone sits in there learning curve with CSS, HTML, PHP or the theme. Many people thank me for making them find the solution, others want it handed to the on a platter. But since I'm volunteering my time, I do have a choice in how I help people. People that have donated and continue to donate get a much bigger allotment of my time and more detailed solutions if they ask for it, but even those people I push towards learning how to solve their own problems. After all, I'm not going to be here forever.
