That’s a fantastic idea and I think you could make it very intuitive.
Listen, you make a very good choice in your focus and I support your choices of where to focus on. I wouldn’t be here if you had spent the time you spent on new features, on fixing old bugs.
So I fully support you and you can keep this bug if you have bigger things to work on. The bigger things will be better for me!
I think moving clips around, adding and deleting them is normal user behavior, like copying and pasting or using the backspace button in a word processor. So this would be like a paragraph becoming bold after I paste some bold text and then use backspace to delete it. But I can’t remove the bold from the rest of the paragraph. And if I click that section the bold attribute isn’t checked.
Why do I say this: because there is text showing up that isn’t anywhere, I don’t have any ability to remove it from the UI (unless, in this analogy, I delete the whole original paragraph I copied some bold text into, which should be unaffected.)
So I would say it’s clearly a bug, same as if you paste a bold word into a sentence, delete the bold word, and the rest of the sentence turns bold - but isn’t shown bold if you click on it, the bold is unchecked even while it’s bold (I’m just making a word processor analogy). This “hidden” bold would be a bug.
You can keep it, but it’s a bug, not a limitation.
One thing I noticed in the video is that the guy says you can’t undo the action.
Since all project files are so small I suggest universal undo and redo should be possible with CTRL-Z and CTRL-Y even if it is not in the undo history: that would let people try things more safely.
Just save a scrap file before each action. This is video editing, text files must be tiny. Undo1, undo2, undo3, undo4, if someone works on it for ten hours have a thousand copies of the project. On occasion if you recover from a crash (rather than user initiated action) you can continue from the last saved undo file. On a clean exit you can erase the undo files.
The reason I suggest this is the very tiny project files, and the fact that many actions don’t have an undo. (Which I was surprised by.)
I don’t want to take more of your time, thank you for making great software
