No.
Current project uses IE & Chrome. Many, many different pages over several sites and sub-domains. Alias file is around 15-20 pages at the moment. One of those being a "global" page which contains common objects used throughout the site but much more basic page identification properties so they work globally.
I use user-defined project variables to set base parts of the URL/domain and then two properties (at least) to identify the page so that I can split the URL and parameterize parts of it and use wildcards where appropriate. Full RegEx availability in object mapping properties would be even better, but wildcards just about do for the moment. Once I have the high level stuff well defined, I then use Aliases that are as short as possible (see above) for the lower level objects. So far, it's working well and problems due to changes have been very, very minimal.
Previous propject had multiple browsers open, sometimes a mixture of IE & Chrome. Using similar, but not the same URL's. I only used name maps for the very high level objects on that one as 95% of the objects on the pages were dynamic. So that one made much heavier use of search and helper routines. But I did find that slowed things down a bit.
