Much of what you are suggesting can be scripted and is not necessarily something that most people will use. In general, if something can be scripted and the number of people who would use it are low, it often will not be added. Some of your suggestions are just a little too narrowly focused, imo. For example, it's unlikely that too many people would care about having a highlight timestamp in their titlebar. Being optional doesn't change the fact that few people would be interested in it, so there really isn't a lot of reason to add that. And that's also not hard to script.
Btw, if you just want to discuss an idea before suggesting it as a new feature as you said at the beginning, you should discuss it in another forum. This forum is for "officially" suggesting things. If you're not sure that something is worth suggesting, it's usually better to discuss it in another forum first to avoid cluttering this forum with suggestions that you later decide weren't worth suggesting.
