In ArcPro, model builder has a really useful "quick link" to tools you want to add to the model canvas. Click on the down arrow below Tools and then start typing to filter the tools, as shown below.
Whilst it's a great way to get to the tool you want to add to the canvas, I find it clunky in that I have to take my hand away from the mouse, start typing and then when the tool is found, go back to the mouse and double click to actually add the tool.
My idea is simply either a click of the return button on the keyboard or a single click adds the tool, this would speed up it's usefulness as currently I feel there is no performance gain in this UI. It's a nice addition but as it stands, frankly no better than dragging 'n' dropping from Toolbox. This minor tweak to it's usability would make it the "go to" approach for users who regularly build models.
