Отлично
Was annoyed by Google Calendar not offering more granular theme control. Loaded up your extension & now I've styled the weekend calendars with ease. Thanks!
Отличный инструмент. Большое спасибо. Обязательно поддержу. P.S. Как одно из направлений расширения, могу рекомендовать сделать ресурс с пополняемым каталогом готовых скриптов, для тех или иных сайтов.
Одно из лучших расширений в своем роде. Не стесняйтесь поддержать автора, знаю не понаслышке, насколько низкий уровень добровольной поддержки у бесплатного софта.
It lacks importing in bulk of firefox's @-moz-document rules. I have them a lot, so entering them manualy is disgusting.
gracias esperemos sirva su aplicaron de java
Great! It would be lovely if I add name or description for each snippet. A google sync would also be perfect!
Great editor, normally i write my snippets somewhere else but this has the features i need like autocomplete, line-copy/move and multiline editing.
I tried several extensions Some of them were quite good But this one is really THE BEST Thank you VERY MUCH.
User CSS has better interface but this one is more powerful
