With this background and usage - I was wondering what others would recommend I do.
The background/usage you describe provides the answer, doesn't it? Your use of "invest" suggests you don't want to sell your M equipment and there's nothing else you can attach a M lens to and use with AF etc. (or attach it to period - or is there? Maybe to M43 w/out electrical connections?); plus you seem to want to keep within the general size parameters of an M. Given all that, your best option is likely to import an M3, provided reviews suggest that it's fixed the problems you mentioned. (They drove me nuts and I sold mine not much more than a month after buying it - weirdly, I sold it for more than I paid for it.)
The only alternative (aside from making yourself like what you have) is to ditch it and start over. If size really matters the new Panasonic LX100, a fixed-zoom more-or-less Micro 4/3 may be the best option, but I suspect its image quality won't be quite as good as an M's. Micro 4/3 MILCs can be pretty small, but as a system it's far from inexpensive. The Sony a6000 is a very good and very cheap aps-c camera, but how compact and cheap the system you build around it ends up could vary quite a bit (its cheap kit lens is small but nowhere near as good as, say, the 22mm EOS-M).
