Rules run in a fixed order: control chars & HTML first, then trim, drop empty lines, collapse spaces, remove specific chars, finally normalize newlines. Great for cleaning messy text copied from web pages.
新增「模式删除/替换」：用通配符 * 匹配任意内容，例如 [[*]] 可一次性清除文本中的 [[11]]、[[1]]、[[5]] 等标记；在「替换为」中留空即删除，填 $1 可只保留 * 部分（如提取方括号内的数字），填 $& 保留被匹配的整体。勾选「跨行匹配」后 * 可跨越换行，能整块删除以 [[ 开头、]] 结尾且中间含换行的标记。New “Pattern delete/replace”: use wildcard * to match anything — e.g. [[*]] clears marks like [[11]], [[1]], [[5]] at once. Leave “Replace with” empty to delete, use $1 to keep only the * part (e.g. the number inside), or $& to keep the whole match. With “Cross-line” on, * spans newlines so a [[ … ]] block containing line breaks is removed as a whole.
