Allow for some way to customize filters

This comes mostly from the need to filter out certain applications that are generated by other programs and are not meant to be launched standalone.

Steam generates Steam Linux Runtime x.x (xxx).desktop files if you install the Linux runtimes. I think the desktop files are required to make it work. These are located inside of .local/share/applications and get re-created if the runtime gets updated via Steam.

Would be great to have some way to just ignore certain files: glob, UI menu with checkboxes and search function, list of names.

I would say steam should not install file here, because this directory is used to filter theses files

I agree. I would also argue that for cases where you have packages that do install these files, it would be great to have some kind of filter mechanism to circumvent this.
