More great ideas!
Here are some comments to posts I've seen so far:
You'll be pleased to hear that some of your suggestions (or very similar) are already on the list, and others are things I'd like to keep in mind for the future. Some (the stopwatch and the manual counter) are so good for this project that I've just spoken to Mod Mark and we're going to squeeze them in

They're really good examples of how a little effort on our side can be a worthwhile benefit for you.
I know it's frustrating to have things to suggest for a project and only hear about it after we've designed it, but Mod Emilee has run threads for just this kind of thing on the misc/other suggestions forum. Sorry if you missed them.
At this stage there won't be any support for putting rewards in your player-run events. I know you'd like to and I'd love to give you that ability, but so far we haven't found a way that we can be sure would be safe against real-world traders.
This project won't change anything fundamental about the way Clan Chat works. There are loads of things we'd love to do to improve the support for clans but unfortunately the way it currently works means that making any change would be a huge project. That doesn't mean we won't keep looking into it, of course, but it does mean it won't change soon.
Above all, thanks for your suggestions and please don't be offended if you don't see your idea in game. Some things need to wait for a different style of project, while others are much harder to make than you'd think (the Engine moves in mysterious ways) and you'd get more benefit from us doing simpler things instead. Some are definitely going on the list of things to do if we get time later
For now though I need to get off the forums and get some coding done, otherwise you might not even get these

Keep the ideas coming.
