Currently, I only develop Firefox addons.

I will fix it if there is an issue. The divider must be changed from the Options Divider "Choose the preferred text divider". Please post to the support for further discussion.

It has been requested and planned for future updates.

The notification goes away after a while and that is controlled by Firefox. The problem with options deselect notification pop-ups, I will fix and upload a new version shortly.

I don't actually make addons for Chrome, only Firefox.

There is no limit on the size. If you notice one, please post the details to the support topic so that I can investigate.
- Custom keyboard shortcuts are already done for the next release
- Date & Time are already done for the next release
- I can increase the URL wrapper limit. No-one had asked for it before.

Update: There was a limit imposed by Firefox (not the addon). A bypass was added to the next version.
