Who is this question to? Sounds like it’s you who’s whining… :rolleyes:
Anyway, to answer it - in my case the thing that bothers me about Renoise and that I think will never be resolved is the rigid structure of a pattern, i.e. the fact that all tracks are tied together horizontally, so whenever I want to do an arrangement over time I need to copy & paste or cut the parts in unused tracks, I need to keep track of the automation per pattern (because there’s no such thing as global automation) and even within tracks I usually have musical loops of different length: from very short (like 1/8th of a pattern) to very long (spanning several patterns). Considering I don’t have a lot of time for my music writing hobby (2-3 hours / week if I’m lucky) it becomes really difficult to actually complete anything, because I simply forget what was where. What I was hoping for Renoise would get eventually is (varying length) tracks detachable from patterns, organised as clips, ideally with separate automation clips. Something like Buzz Tracker’s sequencer, but hopefully evolved. I love the tracker interface of Renoise to enter & edit notes, I love the flexibility and quality of internal FX, sample-focused instruments, etc., but as soon as I have my draft idea done I’m getting stuck with this mind-numbing, tedious copy / paste / delete loop that’s simply killing my workflow. Instead of just writing music, I feel like I’m doing some esoteric programming or creative accounting. That’s why I turned to hybrid clip & timeline -based DAWs (Live, Bitwig), even though VSTi-s or the pianoroll are an alien & foreign concepts for me. I bought Renoise only recently (when v3.1 was published) and will definitely come back to it once in a while, mostly to quickly get some things done that are more complicated to achieve in “traditional” DAWs.
Happy now? 
Although your reply was intended to someone else, I agree with the stuff you brought up here. Interestingly, I’ve thought about exactly this lately as well.
The tracker interface could indeed be more intuitive if it’s clip-based, it’s right on the point. As you mentioned, not only one has the freedom to shrink and expand certain clips on different tracks etc, but it would have some other great advantages over the piano roll and the “old-school” tracker view respectively when done correctly. I’ll try to explain this further, to ensure some may have missed this brilliant idea.
Basically, this is just how a traditional DAW works - except that when you select a clip there’s a tracker-styled editing in the second window, instead of the piano-roll editing. You can however come somewhat closer to this with Redux + a DAW supporting the clips-timeline. But clearly, it’s not the same thing either. I understand there could be some technical limitations to make it work with Redux, but what do I know.
Needless to say, I would really appreciate a feature like this in Renoise (or another DAW with a vice versa feature). That way you can edit and view several clips side by side, although the tracks themselves aren’t necessarily next to each other; just select two-three “tracked clips” and get visual presentation (as long as they correlate on the timeline).
Example: Useful for manual arpeggio-input for a clip, while a clip containing some pad-notes being revealed as a guide ( if you don’t have the best memory of what you’ve done earlier :lol: ). In these cases there’s not necessarily to select, for instance, all the drums tracks while editing the above example = more visual space for the above task, for the moment.
Meaning, with the “old-school” tracking view in mind, you rather have to be a bit lucky if the arp and pad-tracks happen to be next to each other. It’s quite cumbersome to move tracks back and forth, instead of just quickly selecting clips.
So, in theory this should be even better than a piano roll and an “old-school” tracking view for certain purposes. With a piano roll it sometimes just looks messy when selecting several clips simultaneously, depending on how similar the notes are (in a tracker view this is never a problem).
And on the other end of the opinion-spectrum; just add a bunch of tracks with long clips and select them all.
