Once thing that I miss in SQLyog that I have had in the MySQL Query Browser is the ability for each tab to has its own result set. This allows me to run multiple queries and easily flick between the 2 result sets and compare the data. Instead I have to keep pressing F5 and running the query again.

Is this feature already in there somewhere but hiding?

not a new request!

It is not there and not hiding! We are considering a feature to make a RESULT-tab 'sticky', so that it will not disappear when you are executing a new query.

But pls make it possible to turn off this feature in the preferences

@Tom .. nothing decided yet. And it won't be in 5.2

But my personal idea is a small icon on the TAB itself that works like a 'switch' sticky/unsticky.

mhm,
for consistency considerations, shouldn't be the result tab than connected to the query-tab, so if the query via query-tab is changed, the concerning result-tabs should be shown and the result-tabs not from this query-tab might somehow hidden or greyed. otherwise it could be quite confusing pressing a query-tab but having the result-tab from a different query-tab, especially if you do have result-tabs from both query-tabs.
