I was thinking that for icon sets, it could be nice to have an additional XML tag for additional "keywords" to aid in searching for icons. Basically like a list of alternative names (maybe comma separated or something) that could match the typed text.
Sometimes if I make a new command button and am looking for a good icon that will fit out of all the packs I've downloaded, the icons might not have very descriptive names in the first place, the term I think to search for isn't the one used by the icon name.
Like an icon of a magnifying glass might be called "find" whereas I would have typed in "search". Or I have another icon of a command prompt called "cli" where I would have searched "terminal" or "command" or something.
In the days of AI it will be easier for someone making an icon pack to just give the xml file to the AI and tell it to add in some synonym keywords based on the name.
