The most frustrating thing is when you are debugging or testing and you accidentally click on the 'x' to remove a session, losing the data and having to repeat the measurement again. Give an option to disable it or remove the 'x' totally. Instead right mouseclick option or a pop-up warning.
That is indeed frustrating. We did implement the option to protect a session Ctrl-L or via the main menu. We did work on making the hit size of the X smaller as well. I think one thing that would need to be balanced is the ability to quickly close tabs that aren't needed and accidentally closing a tab. It seems like the highest frequency case is closing a tab and so we try to avoid adding additional step in that process. Let us know what you think about protecting captures and if this helps in your case.
I haven't seen that option yet. It is indeed what i am searching for. I am gonna try it, thank you.
For your information: accidentally closing my tabs happened when i was switching between sessions or trying to change the name of the sessions. It did not happen that often but was very frustrating when it happens.
I think one other thing that might reduce the chances is if we only showed the close icon when the tab is selected. It won't reduce the issue with editing the name, but if you are switching tabs you would not be able to close another tab with out first clicking on it.
