 - 2026-10-09：ElyTable 的自动筛选（R2.9）。内核会重新推算未命名的自动筛选区：每次打开筛选列表时向下扩到紧邻的数据行（`ExtendDataArea`、`ExtendBackColorArea`，为接上后来追加的行），命令从单格找到它时按连续数据区重算（`ScDocShell::GetDBData`：应用条件、关闭筛选及其撤销）；选区下方紧邻的合计行因此进了列表、随数据一起被隐藏，存后重开的筛选区同样会扩。补丁 `0040-lok-calc-autofilter-keeps-its-rows.patch`：LOK 下已有的自动筛选区保持设定时的行（同 Excel），不再隐式扩展（光标在区内时；光标在同表另一块数据里即按那一块）；单格开筛选时仍取整个数据区。代价：紧贴在筛选区下方追加的行不自动并入，需重新选定后再开筛选。
 - 2026-10-09：ElyTree 的差异按文件类型着色（R2.12）。组件库 7f2ac3e 与 5caf5aa：`DiffViewer` 按路径的扩展名判定散文与纯文本（md、markdown、txt、rst、adoc、org、csv、tsv、log 等，无扩展名同，不着色），代码按语言的行注释记号着色（`#`：py、toml、sh、yaml 等与 Makefile；`--`：sql、lua；`;`：ini、lisp；`%`：tex、erl；其余 `//`），关键字表各语言共用（原先一律套 `//` 的通用词法，Markdown 的 `#`、Python 的注释都被当作代码上色）。同批带入上游的块编辑器跨块选择、浮层滚轮、输入法候选框位置、插入点按设备像素对齐与格式修正。
 - 2026-10-09：ElyMark 的表格（R2.13）。表格的空格与分隔行写法有许多种（`|a|b|`、`|---|`、对齐空格），逐字重现做不到，原先凡写不回原样的表格都成了原文块。现在一块的序列化与原文在把其中每张表格化成规范形式（各列对齐方式加各格的原文，`tables.js` 的 `canon`）后相同，即为可视块（`preserve.js` 的 `kept`），引用与列表里的表格同样；格内有 Milkdown 会改写的写法（`[[…]]`、引用式链接等）即不同，整块仍为原文块，与段落的规则一致。Milkdown 的列表项必须以段落开头，表格作列表项的第一块时无法放进编辑器，照原文块保留。未改的表格照旧逐字写回，改过的表格按文档多数表格的写法重写（`style.js` 按表格的行节点投票：单元格两侧有无空格、是否按列对齐，经 remark-gfm 的 `tableCellPadding` 与 `tablePipeAlign`；原先投票的解析器不认 GFM，表格从未计票），分隔行随之重写（如 `|---|` 成 `| - |`）。
-- 2026-10-09：ElyTable 新插图表的位置（R2.10）。内核按“定位区域”把图表放在其旁的空处；带参数的请求（Ely 经 `FN_PARAM_5` 给区域）原把定位区域取为光标格，图表紧贴光标、压在数据上。补丁 `0041-lok-calc-chart-beside-its-data.patch`：定位区域取请求里的数据区域（多段取并集），同对话框路径取所选单元格。
+- 2026-10-09：ElyTable 新插图表的位置（R2.10）。内核按“定位区域”把图表放在其旁、并挤回当前可见区；带参数的请求（Ely 经 `FN_PARAM_5` 给区域）原把定位区域取为光标格，图表压在数据上或旁边的另一块数据上。补丁 `0041-lok-calc-chart-beside-its-data.patch`：LOK 下有请求区域时，图表放进数据区右侧（隔一列）第一块够大的空单元格（逐列向右找，跨过旁边的数据块），右侧没有即放在数据下方，不受可见区限制；`LokView` 在新选中对象（原先无选中）时把它滚入视口，拖动中的对象不滚动。
 - 2026-10-09：ElyPDF 编辑与缩放不闪白（R2.6）。旧图块不再随编辑或比例变化即刻丢弃：编辑落地时全部当前图块、比例变化时离开视图的同页图块，连同当时的页面尺寸进入“底图”（`apps/ely-pdf/src/backdrop.rs`），按其在页面中的比例位置画在该页新图块之下，直到该页在视口里的新图块到齐、或页面尺寸与旋转变了才释放；每页画什么由 `PdfView::pieces` 决定，绘制与测试同用它。只有改内容的编辑保留底图并沿用已测的页面尺寸（前 100 页以外不再被占位尺寸覆盖）；增删、移动、旋转、裁剪页面与撤销重做（`PdfView::edit_pages`）清空底图，因同一序号可能已是另一页。关闭标签时底图随图块交给窗口释放。原先比较整份尺寸表（超过 100 页的混合纸张文档尺寸表后段为占位，比较失败即全部清空）且只认同比例的图块（编辑后右栏收起、比例变化即清空），都会闪白。
 - 2026-10-09：文档的缩放锚点（R2.7）。窄于视口的文档居中，缩放原按视口坐标求锚点、漏了居中的偏移，锚点随缩放漂移；现锚点先减去缩放前的偏移，缩放后按新的偏移（`LokView::slack`，绘制同用）换回。按键与菜单的缩放（无指针）另保持首页左缘在视口内；指针与捏合的缩放保持指针下的点不动（文档边界以外即止）。

 LOK Calc: a new chart lands beside its data
 
-FuInsertChart positions a chart away from aPositionRange. With request
-arguments (a kit client gives the range in FN_PARAM_5) that range was
-the cursor cell alone, so the chart went right next to the cursor and
-over the data it charts. Position it from the requested data range,
-as the dialog path does with the marked cells.
+FuInsertChart placed a chart away from aPositionRange, which for
+request arguments (a kit client gives the range in FN_PARAM_5) was the
+cursor cell alone; GetChartInsertPos then pulled the chart back into
+the visible area. The chart covered the data it charts, or a block
+next to it. Under LOK, with a requested range, the chart goes in the
+first empty cells right of its data large enough for it, else below
+the data, whatever the visible area; the view scrolls to it.
