1- Maybe I'll add it.
3- It's better you just load the vehicle and re-save. The way I stored infos in .tmv is bad. It's easy to change the .tmv file name, but anyway...
4- The name of vehicle is the name of file, simply. Older versions was 2 fields, one for file name and other for vehicle name, why not be all the same? And yes, the name of author can be saved in .tmv, why not a new name for vehicle?
5- I don't see useful to know the part ID, and if it is useful to you, just hold CTRL to see.
6- I removed it since it became meaningless, because when you hide-show a part in the Manage the vehicle will be automatically repaired (code limitations for better operation), so why would someone pay to repair it? If it were free it would make more sense, but anyway, I could even put it in some corner, which is difficult because I try to avoid too much information in the main menu.
7- I have thought about it several times, but people are literally lazy, nobody is renaming the parts for better organization. The utility would come when the mod is used along with another, such as Enhanced Functions. I just have not done this until today because it will be a bit bad to adapt such functionality in cloned parts, as you mentioned.
8- It's not easy in anyway, and because of difficult I re-made these functions in Enhanced Functions, so, EnhFuncs is the mod for this (and other functions).
9- I dislike how bad is neon of Pimp My Car. This neon mod is very better. I just didn't included in TM because it's limited to only 1 vehicle by time.
10- As I said, very hard to do.
11- I'm planning this for EnhFuncs, this isn't really functional but, for real, even the default SA functionally is fake (the middle wheel of trucks is just visual, not functional). My idea is that it be simple wheels running as it should be, but without collision.
12- The cleo only can do next, not previous, lol. Because of this that mp3 mods is all made by "1.mp3", "2.mp3" etc. I can make something like store all songs in order in memory and so, but it's just a detail in that mod, much difficulty for a little thing, I even like to leave the songs totally random.
13- It's possible, but I don't think it useful.
14- I already thought about it, and this idea of dropdown is difficult, but it should be an interesting challenge to create.
16- It's very hard... Isn't simply select everything at the same time, it is also necessary to know exactly the position of each part (the offset), and even the offset of a part is related to a parent part that is related to another parent part, isn't simple. And why? For a good working, a new hood should be put in place of your original hood and things like that, that is, usually the correct thing to do is that you add part by part manually in each different part of the vehicle instead of get it all together and place it at chassis.
My idea that apparently nobody said: A list of recently added parts to select.
