The reason why ‘Insight’ could be considered useful is certainly its ability to grab files from snapshots back.
For this purpose, it might be helpful to understand the thoughts that led to the behavior of ‘Insight’.
Maybe I am the only one who has problems with it, sometimes it seems to me that I am the only one who would like to use snapshots.
Back to 'Insight’
There are back and forward arrow-buttons to switch snapshots. When I click several times on the back-arrow-button, I can see the content of a folder how its was at a certain time, but time jumps back and forth instead step-by-step back.
Alternatively, I can choose a snapshot from the drop-down-list at the left of the ‘timeline’. If I do so (ex: auto-2017-10-12-13-20-00) it might be that I see the content of the folder as it was at the time of the snapshot, but in the drop-down-list-button is indicated a funny date-time (11.10.17 23:43), which might correspond to the snapshot in some way - but I can’t imagine how is does so.
I would prefer to see what I have selected from the list, and not something what I never can select from that list.
For the timeline-back-forth mode it might be useful to sort the list of snapshots descending by snapshot-date/time.
Another funny thing is that the name of the app ‘Insight’ is translated to other languages. Nobody has done such with ‘Firefox’, ‘Calibre’, ‘Thunderbird’, ‘Evolution’ … The english names of apps rarely make sense, the translations do make even less sense.
Sure, I know I’m a nagger, so I can not avoid myself.
edit: ‘One more thing…’ When I delete a file within Insight I get one of these ‘do yo really want’ messages, even if that file is contained in a snapshot. In caja I switched off that warning for it is needless like a trash-bin in an OS that supports snapshots, so one can get his/her accidentally deleted files back from the snapshot.
