Recently I implemented a customization for a customer to set a default landing folder for Receiver for Web 2.6. As this may be useful for customers who used to follow CTX119550 to customize Web Interface to get this functionality, I am making it available here.
First, follow the instruction here to configure the related Store to be a mandatory store.
Then, configure the Applications view as the default view for the Receiver for Web site as described here.
After that, append the following code snippet to custom.script.js in the contrib folder under the Receiver for Web site (typically C:\inetpub\wwwroot\Citrix\<Store-Name>Web\contrib) and change the value of landingFolderPath in the code to be the path of your desired landing folder.
Your desired landing folder will be displayed after users log in to Receiver for Web.
