Text editors and spreadsheet editors only involve the content that you can see, they are not depending on what the exact context is while a tracker is depending on that, hence you see this behavior in every tracker:
The problem is that you are editing a line here and not a cell, or at least, Renoise is oriented in keeping track of on which line the cursor is and then which track and interprets the content real-time when you move/edit/insert data. If you insert a note, an instrument has to be triggered, a DSP effect has to be applied, not only in that track, but perhaps also on group level or in a send track, which means that at least two more columns on the very same line have to be processed. This cannot be done if the focus is just cell-based.
Perhaps some kind of cell based focus can be done when follow mode is turned off and play and edit positions are separated. (both options are configurable) but i'm not sure this will work if you insert a note, or it will mean that when you insert a note, it will be done silently without any audio feedback, because then such option sounds possible.
I didn't actually follow everything you tried to explain here, but I get the feeling you possibly don't understand what I, settled, and others are saying. The issue is actually extremely simple, and other mod trackers function exactly the way we're asking Renoise to function, so it's not as if it just can't work that way.
Here's an example: say my cursor is currently highlighting line 8 (the whole line, not a "cell"). I want to enter a new note on line 16 (in any channel--the channel columns are irrelevant to this discussion). The way Renoise currently works, when I click directly on line 16, the entire pattern jumps so that line 16 is in the center of my screen, exactly where line 8 was just a second ago. I find that extremely disorienting. What Rxn, settled, I, and others would like to happen instead is, when we click on line 16, only the highlight
moves to that line, while the rest of the pattern remains stationary. The only reason we've brought up comparisons to spreadsheets is because this is similar to how spreadsheets work (when you click anywhere in row 16 of a spreadsheet, the whole spreadsheet doesn't scroll to put row 16 in the middle of your screen. You simply click into that row where it sits, and nothing moves).
There is nothing impossible at all about what we're asking--this is exactly the way ModPlug/Open MPT works, and I've been working that way for nearly 15 years.
Edit: In re-reading your post, it occurs to me that it sounds like you're talking about editing notes live while the pattern is playing. I'm sure many people work that way, but I know I don't, and most likely neither do Rxn or settled. I don't record anything when the pattern is playing, I only add notes when the pattern is stopped, and then I play the pattern to see if I like what I entered or if I want to change something. In fact, this is why I love tracking so much--you don't have to perform anything live in real time, you can craft a song note by note, going back and changing things, moving things, deleting notes, etc. at your leisure. If the way you work is by recording notes live into a playing pattern, I can see why you might think what we're asking is not possible.
