Feature: Workspace Persistence

[bryphe]

I'd like to add the concept of a session to Onivim 2, which would include the following:

• The working directory the user was in
• Open splits / window configuration (which buffers are in which editor group)
• Window size & location
• Opt-in hooks for various features to persist (ie, like Zen mode)

We'd save this information to a specific location in the user's folder, likely as JSON.

On load, we'd pick up this persisted info and restore the user's workspace / session.

Related:

• Once we have these basics configured, we should extend the format to handle hot exit: Feature: Hot exit (persist unsaved changes on quit) #639
• Should integrate with [feature request] tabs as workspaces #440 (when changing workspaces, we persist the current state of the 'old' workspace, and load the persisted state of the 'new' workspace)

Do you mean, save this in the workspace folder, or in the user's config folder?

I would rather save this at the top of the project directory. Just like VSCode and Sublime Text does. That way, I can save it in my repo, wipe and reinstall from the repo and still have the same configuration for editing the project.

Usually that just ends up in the gitignore file since not everyone on the team uses the same settings or even editor.

I like how atom does it which saves it somewhere in the config directory.

Labeled good-first-issue for the basic persistence and restore logic for simple properties like working directory and window size/location. The rest requires a bit more know-how, but can also be added later.
