Three complaints, one cause between the first two.
A line of a PDF is rarely one run. pdf.js splits it wherever the file does
— a font change, a kerning adjustment, a colour change — so a heading can
be three spans and an invoice line ten. Replacing the span under the
cursor covered a fragment and left the rest of the line standing, which is
exactly what a replacement that looks like a copy laid over the original
is. A run is now the whole visual line: the spans that share its baseline
and sit close enough to be spacing rather than a second column, with the
spaces the geometry implies put back between them.
And that line is edited on the page. The dialog that used to hold a copy
of the words is gone: the cover goes down first, carrying the line's own
words at the page's own size and colour, and the caret opens on it. The
cover keeps its words hidden while you type, so the original never shows
through the thing covering it. Escape with nothing changed lifts the cover
again and leaves the page as it was found — no mark, no undo step.
The rotate grip was a square like the resize handles, wearing the open
hand that means drag-the-page. It is a disc with a turning arrow now, and
a cursor drawn to match, since no standard cursor means turn. The inline
style that was defeating the stylesheet is gone with it.
Ctrl and the wheel zoom, about the pointer rather than the top-left, so
the words you were reading stay where they were. A plain wheel still
scrolls.
Three things the editor made you work around.
Text was typed into a dialog and then placed, so you chose a size and a
weight for words you could not see against the page they were going on.
The click now opens a caret where you clicked, in the font, size and
colour the words will have, with the style bar over it; double-clicking a
stamp reopens it in place. Lining a CSS line box up with a PDF baseline is
measured from the font's own metrics, not guessed.
A signature lived in a single slot. There was nowhere to keep initials as
well as a name, nowhere to change the one you had, and reaching for the
tool again simply stamped the first one — which is the same fault three
times: one slot. It is a library now, with redraw, rename and delete, and
the choice is made when the tool is picked up, so placing stays one click.
An existing single signature is carried into it rather than dropped.
The mark you had just drawn could be resized by its handles and not moved
by its middle, because only the select tool let marks be hit-tested at
all. The SELECTED mark now takes a press whatever tool is armed. A press
anywhere else still draws, and an unfilled shape is still grabbed by its
outline — the same rule select has always followed.
Also: words default to dark ink rather than highlighter yellow, which was
unreadable on white and is now impossible to miss, since you watch
yourself type it.
