This is a Chrome Extension to default to searching the subreddit you're on instead of all of Reddit (/r/all).
Reddit has a lot of weird UX quirks, this fixes one that has been bothering me for years. When you're on a subreddit and you invoke the search tool Reddit will search (by default) all of Reddit for your query. If you want to dig deeper into the Subreddit you are on, you'll have to tick a checkbox that will limit your search to the specific subreddit that you are on.
With this extension installed, searches on a subreddit (denoted by the document's href loooking something like reddit.com/r/...) will automatically default to a subreddit search, while other places on Reddit (the home page, for example) will default to a Reddit-wide search.
This extension doesn't override functionality of Reddit, it just saves you the hassle of checking the box so you can still invoke the backwards default behavior by unchecking the box.
Extore is a team of professionals who are passionate about creating extensions for web browsers. This devotion also gives us opportunity to appreciate work of other people. We get inspired by useful, open source extensions made by developers all over the world. Our strong belief is that one should share helpful add-ons with others. That’s why we’d like to present you our ever-growing list of favourite extensions that have inspired us. Moreover, as you probably have already learned, sometimes struggling for the best brings an end to the good. Talking about add-ons it often turns out that an upgrade is worse then previous version. Also it can become really tricky to get back to the beloved version of your favourite extension. That’s why we’re going to make not only the latest, but all versions of our favourite (and we hope yours too) add-ons available for download. No more compromises, just stick to the version you really like!
