This update is all about speed, especially in longer notes. A lot of the behind-the-scenes work Floaters does to lay out and draw text has been reworked. Typing, resizing, scrolling, and selecting should all feel much more responsive.

• Feature → Code blocks now have a copy to clipboard button
• General Resizing notes is now much faster, especially for longer notes. When a note's width changes, only the text in view is re-wrapped right away, and the rest of the note catches up once you stop resizing. This applies when resizing with the mouse, with keyboard shortcuts, or when linked floaters resize together
• General Lines that don't change when a note is resized no longer need to be redrawn
• General Typing in longer notes is now much faster. Calculating where each line and character goes no longer has to search through the entire note
• General Pressing Return or moving to a different line is much faster in longer notes when Process Markdown Automatically when Changing Lines is enabled. It no longer recalculates the entire note each time
• General Removed the brief pause that could happen a couple of seconds after you stop typing in a longer note. The automatic full recalculation added in v0.9 is no longer needed, since partial calculations now stay accurate. Control+Option will still trigger a full refresh if needed
• General Clicking, dragging to select text, and moving the cursor up and down with the arrow keys are much faster in longer notes
• General Moving the mouse over a note is much more efficient in longer notes
• General Text measurements are now cached, so the same characters don't need to be measured over and over
• General Scrolling horizontally (such as in code blocks, or with wrapping turned off) no longer draws every line in the note
• General In-note search highlights draw faster when there are a lot of results
• General In longer notes, undo history and spell checking now wait for a short pause in typing before running, so they don't slow down typing
• General Reduced memory usage for longer notes. Lines far from the visible part of a note no longer keep their drawings in memory
• General Must faster response time when pressing return or adding new lines near the top of a very long note
• General Resizing a longer note with the mouse is now much smoother. The window keeps up with the mouse while the text re-wraps in the background, catching up several times a second as you drag
• General Lines that re-wrap while resizing reuse their already-drawn text instead of drawing it again, and code blocks only redraw their background
• General Pressing Return near the beginning or middle of a longer note is much faster. The text below is just moved down instead of being laid out again, and lists are renumbered without going through the whole note
• General Pressing Return twice in a code block now adds an empty line instead of leaving the code block. To leave a code block, press Backspace on the new line
• Bug Fix → Pressing up arrow while at top of a fenced code block with a blank line above does nothing
• Bug Fix Fixed a memory leak where memory usage would slowly grow the longer notes were edited
• Bug Fix Fixed an issue where removing a heading, code block, or block quote could leave its formatting on the line until the note refreshed
• Bug Fix Fixed code block and heading lines briefly shrinking while typing in them
• Bug Fix Fixed text sometimes wrapping in the wrong spot after changing the font, text size, or bold/italic formatting
• Bug Fix Fixed selection and search highlights sometimes being offset by a few characters on lines below where you were typing
• Bug Fix Fixed tags, tasks, links, images, and files not always updating their selected appearance when selecting with the keyboard or by dragging
• Bug Fix Fixed numbered lists sometimes showing their old numbers after items were added or removed
• Bug Fix Fixed spelling underlines sometimes staying under a word after it was corrected
• Bug Fix Fixed images sometimes appearing as a gray placeholder until the note was refreshed
• Bug Fix Fixed line numbers sometimes picking up formatting, like highlight or code styling, from the note's text
• Bug Fix Fixed in-note search highlights sometimes being drawn twice or in the wrong spot while typing
• Bug Fix Fixed the horizontal scroll area not shrinking after long lines were shortened, and not always reaching new text typed at the end of long lines in code blocks
• Bug Fix Fixed the up arrow key not moving the cursor from the first line of a code block or a large heading
• Bug Fix Fixed the down arrow key sometimes skipping the second line of a code block
• Bug Fix Fixed pressing the left or up arrow key at the very start of a note that begins with a code block moving the cursor before the start of the note
• Bug Fix Fixed Command-Left Arrow in a code block or heading moving the cursor to the line above instead of the start of the line
• Bug Fix Fixed deleting a line in a code block splitting the block in two or leaving a blank line behind
