Feature suggestion: Add a dedicated save file format for "saved selections"

First of all, why can’t you save selections? I dont understand? If it’s frequency over time then why aren’t you able to save those selections to be recalled later? There seems to only be an internal save selection where spectralayers is only able to save the selections once Spectralayers is opened (and only when it’s opened) and when you close the app then all the selections are lost.

I would like to be able to save all my selections in one file format to be recalled later. Or be able to save the selections internally withing the slp project file so I can recall when (said) a random power outage occurs.

It’s indeed a feature that was requested by some users, it will come in a future SL7 patch. Projects will likely save selections internally (and maybe externally as well, if some specific file format makes sense for that).
