Here are a couple of things the actually get on my nerves in FH5. I thought I would just suggest them in case someone feels the same.
Sort Rims by weight - I want to get that last point on the Car and want to get a lighter Rim. I have to scroll through all the Rims to get one that I like in the weight that I want. It would be nice just to sort it by weight. One can even add other sorting criteria like brand, for example.
Make it clearer what type of race it is before an event - This is especially anoying on convoys. If someone joins an Horizon Tour even, it only shows on top the restrictions, but not the exact type of event. I often take a Road car to a Dirt event for example because it says like “ A 800; Modern Sports Cars; UK or something and I assume it is a road race.. And it isn’t..
Favorite Groups - in Order to sort by type of car or some other criteria. (Let Users create more groups and rename them). This is to allow different types of cars favored for Dirt, Road, Offroad, Different Classes and so on.
Quit Events after accepting them - As an example, if I sign up to an Horizon Tour event, I cannot cancel it manually. Only by accepting another event. I cannot simply return to Freeroam.
Add Proximity Chat - This is a no brainer. Just make it toggable.
Chat Options - The Forza Link is extremely limited. At least some kind of Chatwheel. Normal Chat would be awesome with some AI moderation, for example.
Feel free to add some more suggestions.
