«urltrans» work quite well for my case. It's hardcoded as an array in my plug, so I inject it in $cot_urltrans right in the code.

	$my_urltrans[] = array(
		'params' => cot_parse_str('mode=catalog&gfx=1'),
		'trans' => '{!$mode}{$_area}/{$c}/{$s}/{$typ}/{$vp}+{$year}+{$month}/graphics/{$mg}/{$bt}/'
	);
// and so on

$cot_urltrans['myplug'] = $my_urltrans;

But had another inconvenient thing. As I use shorthand style of call «cot_url», like cot_url('myplug', 'mode=catalog'); // other parameters added automatically from global scope as noted in urltrans

So I trapped myself to cot_url_custom. If urleditor not installed - my code will not work.

And anyway I must write a cot_url wrapper to autimatically send all long chain of parameters to cot_url().

Any way there should be a clear solution to extend «handly url» composing. I mean «i18n» block hardcoded in cot_url_custom is not pure style.

I think I can solve my needs with custom urltrans. So question is: can I add custom url rules to «urltrans.dat» via web form or must editing file direct in filesystem? 

In my case (already using Handly preset of URL editor) I can't do this as «PHP does not support function overloading, nor is it possible to undefine or redefine previously-declared functions».

Some kind of a solution may be adding a hook to cot_url_custom (from URLEditor) as we have in cot_apply_rwr() for adding costom rules to it.

My plugin uses complicated url like:  lang/plugname/subcat/type/product/params/mode/

I can use Hooks=urleditor.rewrite.first to handle it and transform to actual parameters. But is there any way to compose url with my rules like cot_url does (by hook or else)?

I can write own plug_url function, but it's not convinient to pay attention where to use cot_url and where plug_url.

How I can generate with «cot_url» propper link for call ajax part of a plugin ? (I mean «plug.php?r=plugname» or something like this).
