The Sourceban Augmented Moderator Steam Addon is a small plugin augmenting the Profile and Friend List views when browsing a user on Steam. It is intended for Community Moderators/Admins frequently using Steam Profile pages to check the creditability of players.
On the profile page it simply adds the Steam-ID2 (in the right pane, under potentially listed VAC/Game Bans). In case a SourceBan++ installation is linked, the SteamID is a link allowing to directly search the SB database for this user.
The Friend List page now loads substantially slower due to a lot of background Steam API requests. The benefit however is that friends are now sorted according to multiple queryable criteria. The idea is to make researching this profile's smurfs/mains and/or VAC banned friends easier.
Additionally in this view ban data is augmented for each user and a small orange area serves as a link to search the (optional) SourceBans++ installation for the corresponding user (similar to the main profile page).
At the moment I do not intend to publish this Add-On as an official Chrome extension. In order to use this, pull it into any folder (or extract a downloaded tarball), go to Extensions manager in Chrome, enable Developer mode (top right) and use "Load unpacked" to open the folder of the add-on. Pro Tip: Read the entire source code before adding extensions by random strangers.
After installation, click on the Add-On button to open preferences, paste your Steam API key (yes, you need one) and optionally paste a link to your SourceBans++ installation.
Apart from the SourceBans link and the Steam API key you have the option to automatically substitute the leading 0 in your Steam ID2 by a 1. While this flag usually signals the community visibility state, some Source Bans installations need to be queried using always a 1. In general you should know whether or not you need this option.
Querying the Steam API (especially things like the Community Level) takes quite some time. It is therefore a matter of balancing load time versus quality of friend list sorting and displayed user data. Since I do not think that I found the sweet spot yet this balance might shift with future commits.
