MSOutlookit is one of the neatest pieces of software for being a stealthy navigator of reddit.
How to use it? I’ve highlighted the only section applicable for browsing. By default 8 subreddits are included under the inbox tab. Click the subreddit you wish to browse, and your “emails” are the posts.
Once you find a post you would like, the threads comments open up in the right pane. After that, you’re set for sneaky browsing!
