ISO Icon Browser Usability Improvements

The ISO Icon Browser in Qt Creator contains 7000 (so I'm told) icons. It is quite difficult to find the correct icon from such a large list and often some guesswork is needed to do a search by name. For example ABS works in some case but "anti-lock" is needed for others. 

Suggested improvements:

1. Allow filtering by category. As a user I'd like to see which "Product types" exist and then checkmark those I want to see in my list. I'd then like to have a search capability that searches the title.
2. Some items in the list do not have a product type, for example "Icy road conditions" and the "Tyre xxxx" icons. Why is this? Was there an error importing these?
3. As a user I want to know which icon standard these icons come from. For example "The 8th edition of ISO 2575:2010 cancels and replaces ISO 2575:2004, which has been updated with new symbols for functions added in the light of evolving technology." Which version are we using?
4. I see the drop down search filter for "url" but "url" never appears in the right hand description pane. This is confusing so this feature should be removed on the basis that it is useless or the url should be added if that adds value (which seems dubious but open to persuasion).
5. Same as above but for "Registration date"
6. Same as above but for "Function Description"
7. Similar to above but for "Orientation Dependent" though in this case that field is displayed in the icon information panel though it always seems to say "no". If that is true then the filter probably doesn't have a useful purpose.
8. If the filter has no matches then the text "No icons match the filter" is displayed. While this is good it needs to be placed further down the screen so that it doesn't overwrite the selection boxes.
