The option in Settings->Database->General titled "Show warning before running potentially unsafe queries" is useful but too inconvenient when applied system wide to leave on. I would like to have this feature enabled if connecting to a shared development DB or a production DB, but when I'm developing otherwise it's annoying to keep throwing this up on routine operations.
It's a small thing but if this could be moved to an attribute of specific DB connections so I can customize it it would mean that I could make use of it. The existing option could potentially either override specific settings or provide a default (latter makes more sense to me).
It's not a big deal but the rest of this software is so good the odd problem really stands out! :)
