Nautilus 有它的notes-for-files
Tomboy 有它的注释linking-ideas
屏幕本身有它的sticky notes
是否有一个应用程序可以记下特定窗口的笔记？
... 可能基于窗口的标题，并通过快捷键显示..
答案1
好吧，我又开始学习了......（熬夜和喝很多咖啡）。
最终结果是一个适度可用的 bash 脚本（使用 sqlite db/table），它可以完成我想要的功能……
即根据窗口标题创建注释分组……
它可以工作..但它绝对是“alpha”版本..
所以，我有了我自己开发的应用程序！...我在这里发布它，供任何对“看看”感兴趣的人使用......
这里是：
#!/bin/bash
clearAllDataAndStartAgain="false"
# Name: tinotes (Title Notes)
#
# What does it do? ... Aside from giving me a great opportunity to learn
# more about bash (and sqlite, which I had previously barely touched).. not much ;)
# Actually, it allows you to keep notes, grouped by window title.
# The notes are kept in an sqlite database.
# Each timestamped note-"event" is stored in a row of the main (only) table.
# You can consolidate notes in a semi ad-hoc manner...
# Notes are presented to you in a single editable text file (in Leafpad).
# You must keep at least one "tinotes" timestamp-line at the top of the text...
# All lines above this topmost timestamp-line are ignored,
# including the "title", which is presented upon each viewing.
# If you remove any/all other "timestamp line(s)", those particular rows are
# deleted from the sqlite table, and the text which remains is associated with
# the immediately preceding timestamp-line (and updated as such in the sqlite table)
#
# How do you drive it? .. Just associate `tinotes.sh` with a shortcut-key.. That's' it!
# Just press the shortcut-key and you will be presented with Leafpad displaying
# a "title line" at the very top, and on line 2, is a "tinotes timestamp" line.
# Type your note below the timestamp-line, then Save and Exit Leafpad,..
# NB.. You MUST fully EXIT Leafpad.. the script cannot proceed until you EXIT Leafpad..
# Leafpad is effectively being used as a Dialog-box with "normal" editing capability.
# A warning Dialog appears if another instance of this script is currently running..
# (actually, if another ***tinotes** leafpad window is running).
#
# Caveat: This version is very much "demo-only"...
# It works, but has typical "alpha" bugs...
# I've presented it here, for anyone who is interested in the general idea.
#
# dependencies
# ============
# sqlite3 ,, the notes are stored in a sqlite db.
# leafpad .. to edit/view the notes (no need to re-invent the wheel)
# wmctrl .. to detect if a ***tinotes*** leafpad window is currently open.
# xdotool .. to get the active window's' ID
# xwininfo .. to get a window's title via it's ID.
# md5sum .. to check for mods to the presented/added notes data
# zenity .. for warning dialog(s)
# sed .. versatile!
# wc .. word count? .. line count (here)

嗯，我能想到的最好的办法是进入ccsm并尝试按名称选择窗口（我会从“窗口规则”插件开始）。有一种方法可以通过名称移动或粘贴窗口，所以如果你给窗口取了唯一的名称，而且你很聪明，也许这种方法可行……
