What I love about Lazarus' features

[440bx]

I don't think you selected the snapshot, when you said you did...

There should be an arrow (left to right / pointing to the line) in front of the selected snapshot. => double click to select.

You're right. I went through the process a second time to take snapshots and that time I forgot to select the "history" snapshot.

And then double click to deselect. (or double click another to select that other).

That works!   I didn't think about doing that.

TODO: I want to add a line for the "current" pause.

I believe that's the ideal solution because it's obvious what it does.

Breakpoints have an "Add snapshot". You can set breakpoints to not "break" but "add snapshot". That allows collecting data while the app runs.

Essentially "snapshot-points". Very nice.

Overall this feature is still very basic. There are just to many things that need to be done...

It's like Rome, it takes more than one day to build it.
