No, I don't plan for now. I tried to modify scrollbars some time ago: https://github.com/danyaPostfactum/ace/commit/03c77ee9a8aa2b1304cdb2e26d59b193abdef68c

DOM tree looks this way:
```html
<div class="ace_scroller" style="left: 51px;">
	<div class="ace_scrollarea" style="right: 17px; bottom: 17px;">
		<div class="ace_content" style="margin-top: 0px; width: 1252px; height: 380px;"> ... </div>
	</div>
	<div class="ace_scrollbars" style="overflow: scroll;"><div style="visibility: hidden; width: 1252px; height: 361px;"></div>
</div>
```

But I'm not sure both scrollbars should be within the same div. Maybe separate scrollbars would be better for some reasons.
