HoK: limited number of entries in completions

[rdiaz02]

When I set options new options, many of them are not shown when I press TAB to see completions in the extended hint mode. I think this is due to that menu having a limited size. For example, I do:

plugins.options["caret_hint.tail_key"] = "t"; 
plugins.options["caret_hint.head_key"] = "h"; 
plugins.options["caret_hint.select_tail_key"] = "9"; 
plugins.options["caret_hint.select_head_key"] = "8"; 

but only the first will show. The rest do work, but are not shown in the menu.

Could the size of the menu adapt to the number of entries or, at least, be a user option? Or am I doing something wrong? (I've been playing with the options but I do not see how).
