1) EasySocial supports the ability to filter the stream by application. There is a filter for the GPS Tools App but the icon appears wrong (mail icon vs a map) and the text is the placeholder constant COM_EASYSOCIAL_STREAM_APP_FILTER_TRACKS I've attached an image below

2) In the backend there's an area for you to place a description of your app and it's currently not set but rather just the string constant APP_QUESTIONS_DESCRIPTION I've attached an image below

3) I don't see your app in the EasySocial Apps Directory, you could get a few more sales I would think if you list there ;) I'll be adding a rave review because your component just works awesomely out-of-the-box and your support leaves customers feeling they have professionals supporting them
