As said in the title, version 7.51 is better than its predecessors.
Snapping is more reliable, without surprises. However, some problems still remain and were left unaddressed by the programmers:
1) The "ALT and the hamburger menu" problem is still there. Pressing ALT to anchor a clip also invokes the hamburger file menu. Windows moves keyboard and mouse focus away from the timeline, to the menu. Very annoying... I would kindly suggest, if possible, to appoint another key (other than ALT) for the menu.
2) Clips can be resized only from left to the right.... Resizing "right to left" causes automatic snap of the next clip, even if ALT is kept pressed. We have discussed this issue before, I strongly believe it should be possible to resize both ways, and ALT should have absolute priority over snapping.
3) In projects with many short clips, there are severe program delays... I do not refer to the preview window, but to the entire program. Delays in button and menu selections, delays in the control console. My latest project is a 7 minute piano lesson of a song, with many small clips. Unfortunately the delays makes it impossible to edit anymore... I cannot figure out why, but the bigger the project, the bigger the delay. A memory usage issue? I installed a real time mem-cpu counter and it reports memory 43%, CPU 7%. It is not that much, therefore it must be something else. I installed a top-line video card with 4GB DDR5 but still, no noticeable improvement. Maybe too much automation and gadgets overload the software?
4) The "beat white lines" are haunting me even in this version.... There was supposed to be an option to disable them, but I cannot find it. Anyway, at least they are dotted and not so visible...
5) It is not of this version, but what happened to the "track lock" buttons in the timeline? Were they removed for a reason?
6) The small all-time emerging gadget-window "split / start /end time", could be annoying, since it is pressed by mistake and messes the timeline.
In conclusion, the biggest setback (from my point of view) are the delays I mentioned above, and I kindly put it at the programmer's attention.
