Nice suggestion. I did try to implement a more minimalist interface with
variable overlays.

Which can be enabled with the following.
(setq dape-inline-variables t)
(setq dape-on-start-hooks nil)

Second screenshot in the README.org, it's more inline with edebug. But
there is some issues with placement and variable lookup. The current
implementation relies on regex and font lock to search for symbols.
If that work could be offloaded to Eglot/lsp-mode via xref (*I don't
know if lsp support it). But currently that is not possible because
Eglot only supports looking up reference at point.

Fixed.

"dbg" is nice and sweet, but I think it's a + for discoverability to have
dap in the name of the package. How about eldap? If it should signify
a connection to Eglot, maybe Ebug or even closer Dpoly? Or maybe a
reference to Grace Hopper, hopper.
Personally I like eldap, probably because it feels familiar.
