What's Changed
新功能
1.剪贴板里的文字可以钉成文字钉图，能整体缩放和标注，双击选词、三击选整段。
2.图片钉图按 T（「钉成文字」）会把识别出的文字另钉成一张文字钉图，放在原图旁边，原来的「文字模式」随之去掉。
3.序号可以拉出指引箭头，旁边加说明文字，移动时一起走（#143）。
4.马赛克新增「智能擦除」（#139）。
5.剪贴板窗口换成一行一条的新样式，预置「收藏」和「图片」分组，左右方向键直接切换分组，按钮图标统一并跟随主题（#144）。
6.钉图热键能钉图片文件、动图和文件，剪贴板里的文件和多选条目也能钉图；文件钉图能像在文件夹里一样选中和打开。
7.钉图上按住 Ctrl 可以把内容拖到别的程序。
8.设置窗口可以搜索设置项。
改进
屏幕标注打开白板时，置顶的钉图留在白板上面，可以直接在钉图上标注（#142）。
再次钉同样的内容时，已经开着的那张钉图会抖一下并移到最前，不再重复打开；可在设置「钉图」页关闭「提示重复钉图」。
托盘菜单新增「隐藏所有钉图」。
钉图和录屏的画笔也能撤销，并能用工具快捷键切换工具。
钉图可以隐藏标注。
截图时可以用剪贴板往文字框里输入。
钉图缩放每一格都立即清晰，钉长文字和大图时打开、缩放更快。
钉图缩放总能回到 100%，最小边从 50 像素降到 30；钉图有一边不足 30 像素时先确认再钉。
剪贴板搜索快捷键可以自定义；悬停预览改为后台加载，也能预览图片文件；切换筛选分组不再卡顿。
长截图时鼠标停在预览上，预览会变淡。
修复
修复钉图缩小后，复制和另存为得到的是缩小发糊的图的问题。
修复截图后钉图的上下顺序被打乱的问题。
修复几个窗口叠在一起时，按键被截图窗口抢走的问题。
修复钉成文字后字号比原图偏小的问题。

修复剪贴板用滚轮滚动时，预览停在旧行的问题。
修复横向长截图的预览压住滚动条的问题。
New
-
Text in the clipboard can be pinned as a text pin, which can be zoomed and annotated as a whole; double-click selects a word and triple-click a paragraph.
-
Pressing T ("Pin as Text") on an image pin pins the recognized text as a new text pin next to the original; the old "Text Mode" is removed.
-
Numbers can pull out a pointer arrow with a caption beside it, and they move together (#143).
-
Mosaic has a new "Smart Erase" (#139).
-
The clipboard window has a new one-entry-per-row style, preset "Favorites" and "Images" groups, Left/Right arrow keys to switch groups, and unified button icons that follow the theme (#144).
-
The pin hotkey can pin image files, animated images and files, and clipboard files and multiple selected entries can be pinned too; file pins can be selected and opened like in a folder.
-
Hold Ctrl on a pin to drag its content into another program.
-
The settings window can search for settings.
Improvements
With the whiteboard on in screen annotation, topmost pins stay above it and can be annotated directly (#142).
Pinning the same content again shakes the pin that is already open and brings it to the front instead of opening another; turn off "Point Out Repeats" on the "Pin" page of the settings.
The tray menu has a new "Hide all pins".
The pen on pins and in recordings can undo and switch tools with the tool shortcuts.
Pins can hide their annotations.
During a screenshot, the clipboard can type into the text box.
Every zoom step on a pin is sharp right away, and long text and large images open and zoom faster.
Pin zoom always returns to 100%, and the smallest side goes down from 50 to 30 pixels; a pin with a side under 30 pixels asks before pinning.
The clipboard search shortcut can be customized; hover previews load in the background and also show image files; switching filter groups no longer stutters.
The long screenshot preview fades while the mouse is over it.
Fixes
Fixed copying and saving a zoomed-out pin giving the shrunken, blurry image.
Fixed screenshots changing the stacking order of pins.
Fixed keys being taken by the screenshot window when several windows overlap.
Fixed text from "Pin as Text" coming out smaller than in the image.
Fixed a new screenshot taking the focus from a text box being typed in.
Fixed undo not returning a slowly dragged annotation to where it was.
Fixed the clipboard preview staying on the old row when scrolling with the wheel.
Fixed the horizontal long screenshot preview covering the scroll bar.
