Two problems. I installed the new Thundebird and I cannot accustome myself to grouping the e-mail into conversation. It is fairy awkward to look for and open the very last message. So, firstly, I would like to know whether one can remove this grouping in the Settings. I cannot find anything on that. Secondly, it is really a pain to come back from the last message in the dialogue of 50 to the Income folder. I need to press the arrow left on the top and see all messages shifting. Disgusting. There is apparently a solution to that buy using a key combination involvin "Tab" but it works chaotically. Please indicate in simple words what the key-combination does this.
