Ability to have default Excluded Folders (not per-project)

(Update: I also opened an issue for this: https://youtrack.jetbrains.com/issue/RUBY-17583)

Hi,

We use RubyMine across multiple machines, with many different projects (which change all the time, with various languages), and reimage our machines frequently.

It's a pain to have to go in and exclude the same folders across projects and machines.  For example, log, vendor/cache, node_modules, temp, .idea, etc.

These are folders that we NEVER want to index, on any project, or if we do, it's fine to opt-in on a project level.

This tedious per-project setup is one of the things that drives people away from RubyMine usage on our team to other [inferior ;)] editors, especially when it results in horrible performance and startup times (e.g. witn it's indexing a billion JS files under node_modules).

It would be great to be able to define a system-wide (not per-project) setting to exclude (from indexing) for these folders.

This could be a glob relative to the project root that would be a "super" Exclude setting to apply across all projects, in addition to any project-level excludes.

Or just a list of directories, really anything so we don't have to keep ignoring over and over.

Thanks,
