> that finding out whether a file has been modified or not might be > somewhat convoluted. I think a way would be to keep track of a clean/dirty flag whenever actions are performed. But since that requires to change code everywhere, including the future modules, if you don't like the idea of altogether, then this is not feasible. So, I'll try to explain another way to suggest something different.
I understand that, by design, there is no warning when I press "Close". I should not have pressed on Close if I did not intend to close. But actually I was referring to a particular case where closing the file is an unexpected side-effect of an activity -- channel managing. Here are the two points: 1. If one wants to switch between two channels, one must check the second one before unchecking the first one, unless file is closed (and all unsaved modifications are lost). I think this is unexpected. Order of operation should not result in irreversible data loss. 2. If one wants to clean channels used for intermediate calculations (extracted masks, duplicated channels...), one must be careful of previously opening at least one channel that will not be deleted in the end. That means, one must visualize the end result of the complete loop before starting performing the first of them, while a natural tendency could be to perform the steps one by one. That requires specific effort of concentration, diverting mind from its main focus (experimental data processing) for something that seems to me to belong to the software: taking care that data is not lost except when the user meant it by performing a Delete action on a specific data field. Therefore, to avoid an unintentional effects during channel management, I would suggest to disable the delete and uncheck actions for the only opened channel, if there is more than one channel in total and exactly one visible. These are only humble suggestions, I hope there is no problem giving them. The software is anyway very enjoyable.
