Hi,

I found a CSS margin issue in the settings-form variation of FormGroup and this affects your extension. I've fixed it in the 0.10.3

@worksofliam Maybe we should go to the newest release 0.11.0 of the toolkit? Doesn't seem to contain any changes with consequences for us - and with the can open... 😉

If you could wait a few more days I would add some improvements.

• Until now the Textarea component had a fixed default width but if the cols attribute is set, the inner textarea element always will be wider or narrower than the component itself. I've already fixed this but I haven't published it yet.
• I will customize the native, ugly, and gray browser button in the file input.

Done.

@bendera Thank you for the CSS fixes and the likes!

@chrjorgensen I've cleaned up the code further and bumped webview-elements to 0.12.0.

Are you able to give it another run through for me whenever you have a moment? Thanks!

[chrjorgensen]

@worksofliam LGTM - I gave it a spin and went through the following, where there is UI:

• connection settings
• login settings
• actions
• custom variables

All looked good and I found no errors.

[worksofliam]

Fixed and tested again myself to be sure and it's all looking good. I am going to merge.

Thank you @chrjorgensen for your review! And thank you @bendera for supporting us with your fast releases :)
