Occasionally I try to give a node a name that I've already used in my comp. If I'm going fast enough, I don't notice that Fusion refuses the name and preserves the old one. I would like to see an option to have Fusion append a numeral to the new name, like it does with a copy-paste operation.

I'd love to see an update the expressions field that encapsulates the parts of the expression that link to other tools and allows the user to right click and goto that tool or perform other actions relating to the referenced tool (not just parameter).

Just as an example for expression fields, here's a screenshot from Apple Numbers. Each of the colored ovals is a reference to another cell in the spreadsheet. Perhaps clicking the little arrow dropdown could reveal the selected field (as checked)...

I'd love to be able to drag out from any input/output connection while holding down a modifier key and get a filtered version of the 'Add Tool' popup menu.
Example: drag from the output of any 3d tool and get a list of only the tools that it can logically connect with.

Alternatively, right-click and drag from the output to an empty area on the flow for that filtered menu (similar to right-click and dragging from an output to an existing node to get a popup list of available inputs)

Normally, when the input to a 2D viewer changes size, the resulting OpenGL quad stays centered where it was previously. I'm not sure what the utility of this is, but I would prefer that the relative coordinate point of the quad in the center of the viewer was maintained, respecting pixel size.

Notice that according to the Merge2D, these images are the same size. If you A|B compare them, they also are aligned. But if you assign them to the same viewer buffer sequentially, the quad jumps...

Would be nice when using the Histogram SubV if the vertical lines indicating 0 and 1 would change, perhaps to red, to indicate that a sample lies outside the range. Normal distribution means the height of the histogram columns are usually small for normally exposed images, so it's hard to tell unless you scale up and zoom in.

Also, any visual indicator of a NAN sample would be nice.

It's awesome that the 3D Histogram SubV supports stereo glasses and such, but sometimes I want to get a orthographic view, and usually that's to compare two axes. So it would be great if we could have orthographic views and presets for top/front/left/etc., but maybe labeled BR/RG/GB/whatever.

It would be really nice if Fusion 9 and Resolve 15's Fusion page supported adding Alembic .abc files to the comp by dragging them from the desktop folder into the Flow area. Right now this drag and drop action doesn't automatically add a new AlembicMesh3D node.

By comparison, an FBXMesh3D node is added automatically to the Flow area when FBX and OBJ nodes are dragged into the view.

Additionally, an added level of polish would be if dragging AlembicMesh3D and FBXMesh3D nodes from the desktop...

It would be really nice if Fusion 9 and Resolve 15's Fusion page supported tear-off menus for the Scripts:/Comp/ folder based Lua/Python entries. This would be a big usability improvement when you need to access several items in a deeply nested sub-menu and don't want to traverse the full menu hierarchy each and every time.

As an example of deeply nested menus (that can't be torn off) being a pain to navigate try this out:

Step 1. Install Reactor 2.0 for Resolve . Then add the Reactor...
