The Quote tag is almost never used while the Simba tag is regularly used (or should be used) so i see no reason why we have a quote tag instead of Simba tab in the Quick Reply window:
Just find it inconvenient to have to 'Go Advanced' for the Simba tab, and for new users, they often post codes w/o the simba tab as they are not aware that it is hidden away at 'Advanced' mode.
TLDR: replace the Quote tab with Simba tab in Quick Reply.
