With the advanced works on Timeline, Mecanim, Animator and the Animation Rigging package, I feel that the Animation Window isn't getting the updates it needs. As a very regular user of said window, I have a few suggestions to improve it. Event Edition Unfoldable Event Timeline When multiple events are happening at the same frame, it is hard, and in some extreme cases, impossible, to select the right event. If the event timeline was somehow resizeable, it would give a larger area to click on the right event. Events editing box selection When editing keyframes, the scaling box tool is very useful to change the length of certain parts. Unfortunately, it isn’t possible to do the same with the events. Being able to select the events along the keyframes would be useful, or, the scaling box tool when selecting multiple events. Copy Paste This one seems self-explanatory, I would really like to be able to copy and paste an already existing event/group of events, the same way we can with Keyframes. Keyframe Edition Auto Looping Frame Tangent Mode For a looping animation, it would be useful to have a third "Auto" tangent mode, that makes a seamless loop. In order to get a seamless loop, we currently have to : Copy the whole animation paste it to the end (so the last frame calculates the "auto" tangent based on the following frames) set the final frame to free smooth (so it doesn't change when we delete the following frame) copy back to first frame (so the free smooth is applied to both the first and last frame) remove leftover frames Window Tools Search bar The scene view, the project view, and the hierarchy view have a small search bar that allows to search items, using spaces to separate keywords. Being able to filter the objects list by word, in order, for example, to display only the "hands" of the character. Interpolation setting when selecting multiple properties Currently, the conditions to be able to switch between Euler and Quaternion interpolation is to have selected only rotations, and rotation that have the same interpolation already. It would be useful to be able to edit the interpolation as soon as one rotation is selected. Folders and reordering Even if they are stored in a subasset of the animation, being able to reorder, and store in folder, different properties, would be more than welcome. For instance, being able to group in a folder all IK Targets Gameplay Variables Particles The order of the objects is currently by hierarchy. While this is logical, it can be a pain when trying to find both “Hand_L” and “Hand_R” for a character. Mass renaming Animations reference their properties by name, so if a gameObject is renamed, the reference is lost. This is due to design, and is a feature I’ve actually used to use the same animation on multiple objects. However, sometimes, a gameObject will be renamed, and in the Animation Window, this requires to rename a lot of properties, as each property can only be renamed one by one. I actually have repurposed some tools in an Asset Store set of scripts in order to be able to do so. Renaming made more obvious I have never met someone who knew that pressing F2, or clicking on the property’s name allowed for renaming, despite it being a very useful feature. They could read the documentation, but maybe a pencil icon/button to edit the name? Colored sections Some animations are complex, and some are clearly divided in multiple parts. These parts can not be visualized in the animation Window. The ability to “color” or even name boxes in order to group keyframes together would be a big plus to make the different steps of an animation readable. For example, in the Asset Store’s “Slate” tool, animations can look as follows: You made it this far Thank you for reading my rant. I tried to be as specific and detailed as possible. To be honest, I have tried doing it myself by downloading the Animation Window on the Unity Cs Reference Git, but due to most of the logic being internal, it wasn't possible to edit the Animation Window (at least, without recompiling the DLL, which is never risky.) After editing it, there are now 11 suggestions! I also don't know how to end this forum post. Thank you, thank you for the work that's already existing on the Animation Window, and have a nice day.
