[Feature Request] Per-collection variable management (or improve the performance of the Environments tab)

[jaydee864]

Currently, variables are managed at a space and environment level. You define a variable at the space level, and can provide a default value and an override for each environment. This provides the level of functionality to meet most needs, but comes with some issues.

I'm in the process of migrating from Thunder Client recently due to them shifting their local environments feature to the paid version, breaking my setup. I had all my secrets stored in the local environment, and then created an environment for each collection that I used to manage all the path and query parameters for the requests in that collection. I've attempted to set up something as close to possible in HTTPie, creating a new environment for each collection and trying to reuse variables as much as possible.

However, with 9 environments and 26 variables (so far) the Incognito Space page takes roughly 15 seconds to finish rendering, preventing the app from responding until it's done. Even worse, the app redraws the entire tab from scratch each time I switch away from the tab and back to it, even if I haven't closed it. I don't need every variable in every collection, and it would be incredibly convenient to scope as many variables as possible just to the specific collection that requires them. I could even restructure my variable configuration and cut down on the number of environments I employ.

Alternatively, if the performance of the Incognito Space page could be improved for large combinations of variables and spaces, such as by only showing/rendering one environment column at a time and adding an environment switcher, that would also address my issue by making the existing functionality more easy to use. If possible, I would prefer the per-collection feature, but this alternative might provide a quick win.

I realize that the intended solution is most likely to create multiple spaces and move each of my collections to its own space, but unfortunately, I can't create even a free account because I can't use any cloud sync features (company policy), so I'm limited to using just the Incognito space.
