What's Changed
新功能
1.文字识别能认出表格，可以在「文本 | 表格」之间切换，按表格复制，粘进 Excel 和文档时保留合并的格子（#41、#53、#145）。
2.识别出的表格可以直接编辑：插入或删除行列、合并或拆分格子、粘贴、撤销重做；带行号和列标，Ctrl+滚轮缩放，选中格子时显示求和、平均值和计数。
3.文字识别窗口可以对照原图，在原图上直接选字，右侧选中的文字在原图上高亮。
4.截图里按 Ctrl+S 保存，按 Ctrl+Shift+S 快捷保存，不弹窗直接存进保存文件夹。
5.屏幕标注可以跨屏画、跨屏拖动。
6.文件钉图的文件夹格可以拖入文件。
7.首次启动向导改为五页，配上功能演示，新增绿色模式（设置保存在程序所在文件夹）。

New
-
Text recognition can recognize tables: switch between "Text | Table", copy as a table, and merged cells are kept when pasting into Excel and documents (#41, #53, #145).
-
Recognized tables can be edited directly: insert or delete rows and columns, merge or split cells, paste, undo and redo; with row numbers and column letters, Ctrl+wheel zoom, and sum, average and count for the selected cells.
-
The text recognition window can show the original image; select text right on the image, and text selected on the right is highlighted on the image.
-
In a screenshot, Ctrl+S saves and Ctrl+Shift+S quick-saves straight to the save folder without a dialog.
-
Screen annotation can draw and drag across screens.
-
Files can be dropped onto the folder cells of a file pin.
-
The first-run wizard is now five pages with feature demos, and adds portable mode (settings kept in the program's folder).
Improvements
Global shortcuts are ordered as Screenshot, Pin, Clipboard, Translation, Screen Annotation; new installs default to Ctrl+1 through Ctrl+5, and existing users keep their shortcuts.
The translation popup has a new "Close When Clicking Outside" (#153).
The clipboard gear menu has a new "Hide Grouped Items from All" (#154).
Path text in the clipboard window is pinned as files.
Clipboard history uses tens of MB less memory, and the thumbnail cache no longer grows without limit (#155).
The Clipboard page of the settings now has all the options from the clipboard window.
The text recognition window is larger by default, can close after copying, and plain text results can be zoomed too.
Fixes
Fixed long screenshots failing to stitch when the picture jitters slightly or when scrolling quickly in a row (#152).
Fixed quick save adding the format to the front of the file name and not saving in the format set.
Fixed the cells in the middle being left out when dragging across a table row on a pin.
Fixed search and filters inside clipboard groups missing entries.
Fixed clipboard history search being case-sensitive for non-English letters.
Fixed open translation windows not following a target language changed in the settings.
Fixed file paths attached to screenshots not pasting into OneNote.
