Increasing the number of suggests shown in omnibox

Question

Is it in anyway possible to increase the number of suggests that your extension may show in the omnibox?

By default it looks like 5 rows is the limit. I've read about a command line switch to change the number of rows (--omnibox-popup-count) but I am really interested in dynamically being able to set this in my extension.

5 rows isn't really enough for the information my extension want to show.

..[historical] detail: since the removal of --omnibox-popup-count flag (http://codereview.chromium.org/2013008) in May 2010 the number [was] hardcoded:

const size_t AutocompleteResult::kMaxMatches = 6;

a discussion two years later on the chromium-discuss mailing list about the 'Omnibox default configuration' "concluded"

"On lower performing machines generating more result would slow down the result display. The current number look like a good balance."

[which is not a very valid argument, considering the probably infinitesimal overhead retrieving more items than the hard-wired number]

why the heck is there no chromium fork that removes stupid UX limitations like this (or the no tabbar in fullscreen mode)^^

Since there is no more --omnibox-popup-count flag; you can use another flag which is new.

chrome://flags/#omnibox-ui-max-autocomplete-matches lets you select a maximum of 12 rows.
