Hi, I just using odin as editor extension, for having a better control over the Unity editor solution. But now I had have to remove Odin from my project, because I had have disadvantages with. - I have a list of [System.Serializable] objects. These instances have a lot if fields. In the Unity solution all the instances got a grouping parent element (named by the first field of the instance), so I can collapse the lot of fields. In this way the Editor works faster and I have a good overview. Odin blows up all the fields, this is the main reason why I had to remove it from my project. - Adding a new entry does not clone the last entry. Makes me just more work copying the values with additional copy & paste operation. If you have a lot of entries, you don't want this disadvantage. This was in my situation as worse as the first point. - Just a bug, expanded the list and tried to change an enum in a [System.Serializable] instance on the last position. This didn't work. I had to collapse the list and move to the last page, then this change was applied. I hope you will fix these issues.
