I've done my best to list these wishes in order of importance and to exclude stuff that was not really that important to me.
I have two sections. This first section is things that will directly affect my own enjoyment of the game and that I find to be a priority.
1. Chatlog for in-game buddy chat, to view chat you missed in prior sessions. And message notifications that survive a game restart.
2. Make car bubble visible in MT again.
3. Improve forest building in Valley, including better visibility of road clips and auto-terraform for forest roads.
4. Chat bug on podium shows old chat and toggles to new chat with "C". This is a new bug since Valley arrived.
5. Multi-environment servers, including ability to play EnvMix tracks online.
6. Valley signs: "Keep left" and "keep right" down arrows for the 4-9-X sign blocks.
7. Fix occasional fps drop when using new ghost mode for opponents.
8. Option to save videos from replay editor with same name as replay.
9. Fix rendering to video of "player labels" from MT in TM2.
10. Valley blocks:
- Tunnel blocks like 2-3-6 and 2-3-7.
- One block tunnel turns.
- 4-1-X and 4-3-X are identical, so make 4-3-X into a variant without the internal poles.
11. Canyon blocks:
- A connecting block that connects 2-X-X at lowest level in new water with 2-X-X on the ground.
- 2-2-X type blocks along the water's edge.
12. Replay recording of track building sessions.
13. Water splashes
14. UI is unresponsive if buddy chat is open and a track intro in the background fails to end. This currently requires a game restart.
Below are things that I've become aware of when talking to other players, especially new players online since the Valley release. It's things that I personally could live without (I guess I'm used to not having them). But I think some of these things are important to mention as they could potentially improve the game overall for everyone, especially new players.
1. Unified server list for all titles and title packs, official and user made. This would help players see the overall activity in MP, not just the title they have open.
2. UI improvements - less clicks to get around ManiaPlanet.
3. Ability to accept buddy requests without restarting MP.
4. Remove the need to use a validation key to spend Planets the first time.
5. Fix or remove "high" quality option from audio tab in launcher as it gives many people problems with car engine sounds.
6. Videos should go to their own folder and/or let us choose the folder when we begin to render.
7. Add thousandths to solo play, replays, official campaigns, vanilla servers, etc.
8. Give option to keep users logged into the player page between browser sessions.
9. Easy access to player keys via the player page.
10. Better looking menu backgrounds for main titles of TM2 and SM.
