where have these features been removed?

both the lookup list height and the console size can only be configured in idea.properties ->


#-----------------------------------------------------------------------
# This option controls console cyclic buffer: keeps the console output size not higher than the specified buffer size (Kb). Older lines are deleted.
# In order to disable cycle buffer use idea.cycle.buffer.size=disabled
idea.cycle.buffer.size=xxx

#-----------------------------------------------------------------------
# This option controls maximum lookup lists (e.g. completion) height
idea.lookup.height=xx

why?
