I mean... you can already open a terminal to the current directory. But I'm not sure why I would want the terminal to be opened inside the file manager?
Sometimes I just need to type one or two quick commands, maybe at the current path. I don't think this is necessarily to do a lot of work, it's just to give some more flexibility. I can see myself tapping F4, typing "chown blabla something", tapping F4 again, or similar because it's quick and easy.
Nothing wrong in having options that some might find useful sometimes. As long as it doesn't bother those who don't use it.
HOW? I looked all over the menus, pop up menu too.
Assuming you're talking about XFCE's Thunar file manager, it's either File > Terminal or Terminal in the context menu for a directory.
If you don't already have it for some reason you can add it in Edit > Configure custom actions. Create a new entry that runs your favorite terminal app and give it %f as the parameter that will take the value of the directory you want. Please make sure to select only "Directories" in the "Appeareance conditions" tab.
You can create other custom actions too, for example I use zenity --question && shred -fu %F to shred and remove a file after asking for confirmation.
I don't have it, and the custom command doesn't seem to apprear anywhere, but thank you anyway - at least I now know it's supposed to be there and can look for fixes
Edit: i've reread your post and Appearance Conditions did the trick. Thank you!
They're the same kind of tab; not a completely different application. Should we also listen to music in Dolphin? Watching video in Dolphin? Edit files in Dolphin? Should we make Dolphin the only app on the system and do everything in it?
Typically, when I open a terminal I want a normal size one, so I can see file listings, scrolling data etc. In my case I would say 99 times out of 100 I want a regular terminal rather than a small one at the bottom.

I mean, yeah. I use Krusader, and the reason why I use it instead of Dolphin is because Dolphin doesn't give me an easy way to edit files and view images. In Krusader, "Edit" is F4 and "View" is F3. (It does open a new window, though.)
Music and video files are easy. Previews, baby! Previews are very convenient. I want to make sure that I'm about to open the correct file. Or I'm trying to find a specific file, and the file names aren't making it obvious. And so on. Now, this isn't something that I've felt the need for, but it's easy to see use cases for it.

I would say that if something is going to take me only a minute or two to do (or less), then it's more convenient to do it from the file manager than to open a whole new program. Technically, Krusader is using kate, etc. under the hood to do all of that stuff, but it's through the Krusader interface.

In your case, sure. But other users are going to have other use cases. Not everybody thinks and works the same way, so what works and makes sense for you isn't necessarily going to work and make sense for other people. That's why I like KDE so much. It's very flexible to the needs of users.
