There's nothing wrong with suggesting ideas for the next update, but perhaps you could make a compilation thread for specific topic. E.g. Tardises.
What tends to happen with these type of threads is that all sorts of random suggestions are made, differing in quality and topic.
It's going to be hard for the mod developers to read through all the suggestions and pick out ones they can implement, which is why we recommend you to make your own threads.
Might I also suggest making this thread in the Suggestions tab, it's more likely to be noticed there.
