Hi Paul,
Will start with the basic token of appreciation for how you handle this forum, requests, the app and etc.

So, my feature requests in this topic are:

When you play the song and use the Clock button to add the timestamp at the very moment it happens, it moves down, which is great. Could it skip Headlines the same way it skips blank lines? First because if you put a timestamp on headline it loses formatting... Also because Headlines are being used to mark a Section (maybe they could automatically follow the Regions... like... when you create a Headline with a timestamp, it would/could link/align with the regions.
Linking Sections and Regions. Using a bit of what I've just said above, if you define and link Regions and Sections, it could even change the background colour of the lyrics to show where a Region starts and ends and follow the Regions you see horizontally.
Timestamp Time-shift Shortcuts. This might be a bit ambitious... but... when the cursor is on a timestamp, maybe some controls to show up at the bottom with basic time-shifting shortcuts like: (+1sec), (-1sec), (+0.5sec), (-0.5sec), (x:x:00) (Zero milliseconds). (MOVE SONG TO TIMESTAMP <<< this would be great... if I could from the timestamp move to that part of the song and resume from where I made a mistake, for instance)
Timestamp Time-shift Shortcuts. This one extends the one above. And make changes to all timestamps within a selection. Like, you make a big selection with your whole Verse section. Then you get some actions that are relevant and will be applied to all timestamps in the region. Zero all milliseconds. +1sec, -1sec, etc.

What I'm finding is, to manage the timestamps, times you click twice on clock and get two timestamps breaking the sequence and making it hard to manage, as you need to stop... move the cursor to the right position, move the song to the right position, play and get ready to insert the timestamp codes again.

All just ideas... would make my life easier and editing more efficient (imho)

Best regards,
