Hi guys,
Unfortunatly, changing icon sizes per-fence or per-icon/etc isn't something I can do. Since Fences was written for compatibility / to work with the existing desktop rather than replace it, i'm stuck dealing with some of the desktop's "truths". And one of those is that, yeah, can't do that 
Selectively removing icon labels sounds pretty neat, but again anything that involves changing the size of an icon gets pretty dicey. The difficulty / level-of-sophistication required to even get the partially-invisible icons was very high. Do I sometimes regreat writing Fences to attach on to the existing desktop rather than rendering / doing mouse processing for it myself with full control? Perhaps. But I'm often reminded of why it was a *good idea*, as well! (See how Fences doesn't "mess up" often/ever / behaves exactly how you'd expect you desktop to behave? And uses very few resources? A complete custom desktop would erase those benefits, as then i'd have to spend loads of time worrying about writing all the little bits of the desktop from scratch, emulating all the different behaviors it has that one might not even notice... not to mention compatibility with other 3rd party software / shell-extensions / etc.)
Sorting is definitely something I plan to do. At some point I hope to introduce a whole concept of "Smart Fences". You'll be able to have them sort based on various criterian (none, alpha, size, date modified, etc), and also choose default fences for certain filetypes / force a sort / etc. E.g. "unless otherwise specified, new icons go to fence 'New Stuff'", "all new Excel files go to fence 'My Worksheets'" (with option to "sort my existing icons based on my smart-fence rules"), or "all new icons created while 'Internet Explorer' is in the foreground go to the fence 'Downloads'". Essentially imagine Outlook's "Rules" for incoming emails, but for your desktop icons.
Alignment, I would like to do, but I don't know that it's a top priority. E.g. align center/left. Do-able, but time consuming. Also scrolling as I have it right now only works vertically, so I'd have to update that entire system to be horizontal on top of writing a whole custom sorting routine. So yeah
But, that one definitely isn't ruled out for some time down the road. Hopefully Fences will still be helpful for you even with the top-down/top-left alignment only? What are your thoughts
