Trying the RC... I'm okay with the lack of built-in GPS averaging, and it's nice to see the app still uses the external version if available. (I kept a copy of 3.0 which is pre-malware.)
But best of all, after much couch-surfing, I see the issue of cut-off texts with MFV4 maps is almost completely gone, as I probably mentioned before. It still happens, but very rarely, maybe 1% as often as it used to.
Map rendering does seem a bit slower, BUT as I think I'd said, I'm perfectly willing to accept that in exchange for proper map rendering; I'm guessing it needs to re-render some tiles to fix the text. Also, I'm testing the RC on an older, slower device, so it's not really a fair comparison. In short, speed is okay, rendering is wonderful.
LoMaps still seem to be V3. Will they switch to V4 at some point? (Sorry if it was mentioned somewhere; I haven't seen it.)
