I like the new format but I would comment on the "feedback as follows. I am numbering them 1 to 6
1. A waste of time. It is very easy to use the cursor keys.
2. Yes could be helpful . The problem with the old system was that the two numbers appeared on top of each other which is not how you would write them and they looked a bit crowded.
3. Why bother? Actually the present arrangement is a slight check as to whether I have actually done the last equation.
4. No comment
5. No comment
6.Sounds good but I rather think that it is not a good idea. I agree that the drop down can get in the way BUT if I am not sure where an infrequently used item is, the last think I want is to have to go clicking all over the place to see each drop down in turn.
I would like to suggest that any changes from here on are only to correct bugs ( If any) and that we should all take a little time to get used to the new format. I like it and I think that Will has done a great job.
