Improved Sticky Labeling Options for Email Threads
I've encountered an issue regarding sticky labels applied to email threads. Once a label is applied to a thread, the only options available are to either remove it from the entire thread or to individually unlabel subsequent emails as they come in.
This became particularly noticeable when I migrated to Proton Mail and imported messages from other platforms. While the initial batch of imported emails were appropriately labeled as "Imported", I noticed that new emails coming into those threads afterward also automatically received the "Imported" label.
It would be helpful to have an option to prevent this auto-labeling for subsequent emails.

When I moved to Protonmail, I imported all my emails from Gmail using the new Import Assistant. Those emails were tagged with a 'Gmail import' tag.
I generally want Sticky Labels turned on, except now any emails that are replies to imported emails (Uber receipts, etc) get tagged with the 'gmail import' tag as well. So to fix that annoyance I have to turn Sticky Labels off.
It would be really nice if you could select whether individual labels are sticky (with a 'select/deselect all' option of course).
