OK Jens, thx a lot for your answer. I just render last 10-50 based on the device "capabilities" (kind a tricky, but an iPhone 4 just shows 15 and an iPhone 6, for instance, shows 50) and then have a "load older" button too... But, even with 50, the final end user impression can be optimized.
OK for mapping both places to the same activity then. Will rearrange code and create helper classes for code maintainability... yes, of course we'll give it a try! ;) Thx a lot.
