Another tremendous improvement Kovid! I'm extremely impressed and pleased with this now.
Some suggestions and bug reports:
1. I agree with The_Ad that the selection handles are too large. I actually do a double take each time they pop-up. Perhaps there's a way to have an invisible/transparent "touch zone" that surrounds a handle that is 80% smaller?
2. The "Search for selection in the book" button requires you to press enter when the search panel opens. Could it automatically apply the search?
3. I agree with thiago that the "Delete" and "Delete Selected" in the main "Browse Annotations" window are redundant - you only need one of them to work for
4. "Delete Selected" in "Browse Annotations" doesn't seem to do anything.
5. "Delete" doesn't seem to work when you have multiple selected in the "Browse Annotations" window. "Remove" in the Viewer's Highlights Pane allows for deleting multiple however. Perhaps synchronize the term in the two windows - either Remove or Delete?
6. I agree with thiago's suggestion/bug report that when you double click a highlight, a line break in a note should show as a line break, rather than putting them on the same line. Same thing in the Browse Annotations window. A single line break works in the Highlights panel of Viewer.
7. We shouldn't be allowed to click "Edit" in the Browse Annotations window when multiple highlights are selected. That would also fix the problem that it only edits one of the selected annotations when you do so.
8. The icon for Quick Highlight in the Selection Behavior configuration menu is still the same as the full Highlight Selection option, whereas they've been differentiated in the popup bar.
9. I agree with jony08's "Suggestion 5: Selecting a highlight in the Highlight panel should show the note under the highlight just like in the Search panel, instead on the bottom of the panel."
10. An old suggestion: show a small icon at the end of a highlight that indicates there is a note, to differentiate it from a bare highlight. Kindle for PC has this and it is very nice. See below:
11. "Edit" in the Viewer's Highlights panel doesn't work if there is already a note. Only if it is a bare highlight.
12. I get the same problem as jony's "Bug 4: Double clicking on the text in the book selects the whole paragraph in 4.22, while in 4.99.10 double clicking only selects one word." In 4.21 I can "triple click" to select a whole paragraph, but it stays limited to one word in 4.99.10.
Thanks so much for your hard work!
