• Big Sky :: Google Readerでもgをぺちって全部全文読んじゃおう。
  • http://mattn.kaoriya.net/software/firefox/greasemonkey/20080225184928.htm

魔改造。
自分はGoogle Readerではてブのコメントで概要を見てから全文取得して読んでいて、
z押してから情報をロードされるのがタルかったので修正。
コメント読んでる間に全文取得されるので見たい記事でzかアイコンを押せばすぐに表示されるようにしてみた。
適当過ぎる変更をしたので動作怪しいかも。

1. 裏で常にオートロードしておいて、ボタンかzが押されたら表示を切り替えるようにした
2. オートロードの設定を変更しないように
3. フラッシュメッセージ非表示
4. livedoorクリップとはてなブックマーク数のアイコン非表示
5. 11/24 取得した本文をhtml内に埋め込んでおくようにした
6. 11/24 本文のロードが終わってからアイコンを表示するように
