dtrt-indent VS good-scroll.el

For #2, I've been pretty happy with dtrt-indent (https://github.com/jscheid/dtrt-indent) for DWIM indentation bouncing between projects.

I have yet to try apheleia, but I wouldn't be surprised if just enabling apheleia, dtrt-indent, and editorconfig-mode (https://github.com/editorconfig/editorconfig-emacs) in prog-mode-hook just did what you wanted.

I have a package (github) that detects the indentation offset and updates the tab-width variable in emacs. Does anyone have a package/function that can use this variable to indent/dedent single or multiple lines?

I haven't tested this myself yet, but maybe M-x term + good-scroll.el would work well

On modern hardware, without native I would encounter micro-stutters here and there, and most frequently while smooth scrolling using good-scroll. Stuttering is non-existent for me on native, so I'm definitely enjoying that. And also less empirically, just general command execution feels a bit more snappy.

I don't know but maybe it requires some configuration but pixel-scroll-mode only led Emacs to freeze. I think a better package might be https://github.com/io12/good-scroll.el, and for images https://github.com/casouri/iscroll

I wonder what the root cause for this is. Most of the explanations I've read revolve around emacs' lack of animation support. For example, the github page of smooth-scroll.el states the following:

It's not often that I publicly display my respect/affection for a certain package. But good-scroll is such a nice enhancement that I feel like anybody who uses a mouse in GUI Emacs MUST try out. The smooth scrolling experience that this package provides is the best implementation I've seen, and the built-in `pixel-scroll-mode` is far from being at the same level (no offence to `pixel-scroll-mode` developers though).
