Description

Quoting @Tantacrul :

One thing we should do btw (just so we don't forget) is a mini design where we ask people on startup whether they want to scan plugins for Audacity or skip scanning entirely.
'Skip this time' would bypass the entire scanning process so users can open Audacity quickly
'Scan plugins' would initiate the scan
If there are plugins to be scanned on startup, we ask this question every time. We'd need a very small explanation too.
"Audacity has found plugins that need to be scanned before use. Would you like to scan them now or skip?"

This might be a provisional solution superseded by #8645
