I have some suggestions for changes in Studio's alignment tool:

1. When you click on a segment, the files move by themselves:

It's very annoying and confusing, I think it would be so much better if the segments just stayed in the place until you want to scroll down or up.

2. In WinAlign there was an option to desynchronize the file scrolling, so for example if you wanted to check only the original text, you could desynchronize it from the target and scroll down only the original, and the target text would stay in the same place where you had left it. It think this was very useful, specially when the sentences that you have to align are not very close to each other, so you have to scroll up or down in one of the files but not in the other. Or when the automatic alignment that Studio does joins segments that are very far apart, sometimes you can't even see one of the segments because the scrolling is synchronized and the segment is too far down and you can't see it, like in the screenshot below.

Besides, when this happens, the lines are so close you can't even tell them apart.

3. The curved lines are more problematic than helpful. If it had straight lines like WinAlign it would be easier to figure out which original segment is aligned to which target segment. Besides, the straight lines never got too close to each other so that you weren't able to figure out which line joined which segments.

4. Here it is not allowed to join one segment with more than 3 other segments, so you have to copy and paste content so that they don't surpass 3 segments, but it would be easier to just join 5 or 6 segments with the other one and that's it. Or to have the option to merge segments instead of having to copy and paste.

5. Here the only options we have to disconnect segments are to disconnect all of them or disconnecting them one by one. I miss the option to disconnect only the segments that we haven't confirmed, because if I start an alignment of a very long file, I confirm segments and all that, but then after I have reviewed 1/4 of the alignment I notice that the rest of the alignment is all wrong and the only options I have are either to disconnect everything and start all over again, or to disconnect the rest of the segments one by one. In WinAlign we had all these options:

We also could select which segments we wanted to disconnect, which was very useful.

We also had all these options to confirm segments:

We could also realign the files starting from the active segment so that whatever we had committed before would remain as it was.

All these options were very useful, so I don't understand why they are not available in Studio's alignment tool.

I hope you find these idea interesting enough to take it into account and implement some changes into the alignment tool, I think it would improve a lot :).
