Does anyone use one of those playmats that turn into a drawstring bag for their big(ger) kids' tiny toys? Things like Legos, or LOL dolls and their 8 billion tiny parts? Is it actually helpful?

We're having some ongoing tidying up struggles, and I'm wondering if something like this might be helpful. I wouldn't use it as long term storage for any one item, just as a quick way to gather and dump a collection of toys back into it's proper box; ensure we've got all the little shoes and things before we vacuum, etc. I am thinking that if the kids realize how easy it is, they might contain their mess a bit more/scatter their toys a bit less.

I'm talking about something like this:
