No way to delete ONLY selected logs in Dataflash log downloader


Unfortunately there is no way to clear ONLY some (selected) logs with Mission Planner Log downloaded.

Some of our clients fly a lot, 8 hours each night 4 flight back to back. SD cards fill up super-fast with logs. It seems from our testing that the autodelete feature in Arduplane is broken for now. https://github.com/ArduPilot/ardupilot/pull/14484

So the only other way to not have "bad logging" error message to pop-up perpetually during flight (as soon as SD is filled up) is to ask the client to clear logs every 2-3 weeks (Yeap, that is how fast it fills up). This would not big such a big deal it we did not need them to keep the logs of the last last 4-6 flight in-case something goes wrong. To use for analysis.
The problem is that because there is no way to just clear/delete a few (selected) old logs, they first need to wait hours to download over mavlink the more recent logs, to have as back, and only then can the press the "clear logs" button.

I would kindly like to ask/suggest to either rename it to "Clear Selected Logs" (and update the function) or to add a new button with that name and function.

**Currently if you press the "Clear Logs" button, they all get deleted**, irrelevant of if there are selected or not.

If this can be fixed, then users can just select all the older ones and leave a few of the most recent ones un-selected. That way there will not be a need to download anything.

Thank you.

Start in the Mission Planner Dataflash log downloader and inspect how the current “Clear Logs” button handles selected and unselected entries. The change is done when users can delete only selected older logs while retaining unselected recent logs; verify that the existing clear-all behavior remains available or is clearly renamed.
