Storyline Timeline - Bugs & enhancements

I'm curious if Articulate employs usability studies to determine productivity issues with their feature set. I've been using Storyline for several years, and still see many timeline issues that should have been resolved or improved long before the current version (v3.98.34380.0). I hope these will soon be fixed, and not just given a "workaround." Specifically...  

1. What's with the current playhead? It automatically jumps to where ever I click within the timeline. Who finds this useful? We're not scrubbing time in the layer stack. The playhead should move only when the user clicks or drags it at the top of the timeline or hits a hotkey to move it to the head or tail of a layer. Instead, the current playhead constantly jumps to the place where I'm attempting to trim or retime a layer or adjust animation timing. What is the point of constantly moving the playhead for non-playback functions? It seems it's always where I do not want it to be, and prevents efficient layer editing. 

2. The paste enhancements (i.e., pasting a layer at the playhead, above the selected layer) would be useful if this worked consistently, but it doesn't. About 50% of the time the pasted layer does not land at the playhead above the selected layer. Is this a bug? 

3. Why is there no auto-fit feature to show the entire timeline within the frame of the application window? This is a basic feature. Storyline used to show the entire timeline when you drag the zoom slider all the way to the left, to the small "mountain" icon, but not anymore. Even when zoomed all the way out, you have to use the scroll bar to get to the right end of the timeline for timelines longer than a minute. We have an auto-fit button for the stage. Why not the timeline? 

4. Centered zooming on the timeline. In most timeline editors, the zoom function operates from the location of the playhead. For example, you move the playhead to time 04:37 and then zoom in to focus on where you're working; the zoom should keep you centered at 04:37. Except in Storyline, it doesn't. Storyline always zooms in/out from the 00:00 point, regardless of how long your timeline is. This means if you're working at 04:37, you do the zoom-in and then must scroll right until you get back to the place where you were working. Who finds it useful to zoom into the place where they aren't working? 

I can't tell whether these are bugs or design flaws. These may seem like minor issues, but they do impact productivity and efficiency with large or complex projects. Is anyone else experiencing these as problems? Does Articulate have any plans to fix them?
