Labs tool is a place where experimental or alpha-stage features are published. You can enable or disable them on per-database basis.
You can find it in the Setup > Database tab > Tools > Labs link.
There you will also find the link to a corresponding idea in Idea Exchange - feel free to comment.
Please note that the features published in labs are experimental. They can be added or removed and their implementation can be changed anytime. Some of them will find their way to TeamDesk, some will not. We would not recommend to rely on them in the production environment.
For instance, if the New Ask the User option is enabled, the additional Ask the User section is shown in the settings of a View.
For example, the Practice Areas column is a multi-choices text column where more than one Practice area can be selected in each Attorney record. So, you can use this column as the Ask column in the filter. As the result, when you choose the required options in the filter and click on the Execute Query button in the view, you’ll see the records containing at least one of the selected Practice Areas.
If you want to filter records by Multi-Reference column (Many-to-Many), the filtered results are different from the text column. In this case only the records keeping all selected options will be listed.
More details about some features listed in Labs you may find and read in TeamDesk blog.
