qtarget has been largely unmaintained, receiving some occasional fixes and tweaks.
There are issues with the ways many features were implemented, some from trying maintain compatibility with bt-target, but mostly janky patches on top of underlying flaws.

Development on a replacement is ongoing at ox_target, which will try to implement some compatibility; however it cannot cover everything and will not attempt to patch poor-design decisions.

Some issues will be patched in qtarget if necessary, but it is dead (and should have been long ago).

• Primary development by @thelindat and @OfficialNoms
• Inspired by, and based on, including using javascript from: bt-target by @brentN5
