It would be helpful to be able to search for errors on specific modules. Now it's only possible to select 1 module. By having a multiselect, it is possible to check on 2 or more modules that you are interested in at the same time.
The other way around, you can "select all" and then deselect a module that is having a lot of errors (which is troubling the error logs) to be able to find the errors you are interested in more easily.
The same would be for the application search.
Same request is useful for applications dropdown
