It depends on the type of facts, but sometimes it’s much easier to verify an answer than to get the answer in the first place. For example sometimes the LLM will mention a keyword that you didn’t know or didn’t remember and that makes googling much easier.
That wouldn’t be so useful for academic papers, which is the use case described here: I’ve never heard of a an academic journal that accepts Typst source, but I know of hundreds, probably thousands, that accept LaTeX.
As you say, they are basically just window configurations, so I do use them ocassionally. If, in addition to remembering an Emacs window configuration I also want to remember whether the frame is maximized or not, I will use frames instead of tabs. I used to put window configurations into registers, before tabs existed, but tabs are better because when you put a window configuration into a register it even remembers the location of point in every buffer. This means that when you restore the window configuration from the register, points get restored to where they were when you stored the configuration, not to the last time you were using it. In this sense tabs are like window configuration registers that automatically update every time you switch away from them.
Tabs only have “useless UI elements” if you want them to! This is Emacs, after all. To use tabs without displaying any UI element set tab-bar-show to nil.
One small thing I liked in the new version is the grep-use-headings user option, if you set it to t, then grep buffer lists the search results with headings, one per file, instead of repeating the filename every single time.
There are commands
which-key-show-major-modeandwhich-key-show-top-level, which you could use. On the embark side, there isembark-bindingswhich by default gives you bindings from the major mode and minor modes, but withC-uwill give you global bindings.Agreed.
Only because I didn’t think of it!
