That is better. The flow for depot - buy vehicle, set schedule, promote to line is smooth now. The only problem is, that after closing the line and schedule windows, the depot still says "no schedule". But if I reopen the schedule, it is there, even with the new line mentioned. But the depot does not recognize the schedule until the depot window is closed and opened again. Even then it says the vehicle has "individual schedule", and not the newly created line. But sending the vehicle out of depot works and it goes on the intended line.
Is it possible to not stop the convoy when I switch to the schedule tab? That is not very nice (and especially if ported to extended - it will switch vehicles to drive by sight). I admit that in this case the apply button would make sense. Or an edit button, that would stop the vehicle, enable editing, and change itself to apply/revert button. Or better if editing the schedule would be possible without stopping the vehicle. And it will stop only after leaving the dialog/tab.
Switching between tabs should not affect the convoy in any way. Also there used to be information about the line a vehicle is running, with a link (triangle) to the line management, where one could examine the line. Now there is only a link to Edit the line, but not to view it. Would it be appropriate to show the line (or info that the vehicle has individual schedule) in the common part, below the destination line?
And one more thing - I tried editing the schedule. Added one more stop and reverted. At that moment the invisible window containing the list of stops shrunk to minimum, so only two stops were visible, an scrollbar (that was not shown before) appeared. See scrreenshot
