The new look is very nice... however, it was much easier to see which script was enabled or not with the previous layout. Is it possible to have an option to always show enabled/disabled indicator? Also, is there an option to disable cloud uploads entirely, or have the ability to disable cloud uploads on all scripts? Having it default "Off" would also probably be a good idea. I don't know whose cloud that is or where it is, but I do not consent to any of my stuff being uploaded anywhere without my PRIOR consent. Also, is it possible to have multiple scripts on the same page, or one script on multiple pages yet? Setting things up for "domain.tld", then "domain.tld/*", then "*.domain.tld" and "*.domain.tld/*" just to make them distinct is getting old.
Excellent update!
Большое спасибо за расширение!!! Подскажите, пожалуйста, как подключить и использовать модуль Vue в скрипте? Никак не получается почему-то.
É uma excelente ferramenta e uma mão na roda para os desenvolvedores que trabalham através do DOM.
This tool has been amazing. However, after the latest update I am unable to save any changes. EDIT: I've found that I need to add something to the Javascript section to be able to save the CSS. So I just put a space into the JS.
Does not work after the last update on 31st January. Tried running in Isolated and non-isolated mode, both returned the same error, the objects I defined are not available from console.
Muy util
Не работает в Microsoft Edge, очень разочарован, а в целом прекрасное расширение
Very easy to use and works perfectly. JQuery injection supported
O fato de já possuir algumas bibliotecas (tipo JQuery) prontas pra inserir, e espaço pra vocês acrescentar as que quiser, faz dela a extensão mais prática pra essa finalidade. Parabéns e obrigado!
