Some icons are not clickable

Hi! There are several icons I want to ask about:

1) The following 'Text' icon is not clickable in sketcher:

I have investigated the related issue - https://github.com/cheminfo/openchemlib-js/issues/139
And in response you have provided the link to the documentation, but from this documentation it is not very clear is which certain situations this tool should become available

And do I understand correctly, that if the text has been added it will only be available as a part of the drawing in editor? Or can it be saved somehow?

2) ERS tools icon also doesn't react neither to hover nor to clicking. Can you please specify how to make it available.

I also want to mention that we show editor in the dialog. And to make atom properties dialog available we had to add z-index to dialog box class (workaround from this issue - https://github.com/cheminfo/openchemlib-js/issues/117). Maybe to make ERS tools available some other class should be updated?

3) in this issue - https://github.com/cheminfo/openchemlib-js/issues/117 - you mentioned that by pressing 'q' when hovering over an atom some additional atom properties open. But I cannot make it work. Nothing happens when pressing 'q'. Can this also be related to z-index?

Start by reproducing the Text, ERS, and atom-property interactions in the sketcher when it is shown in a dialog, then review the related issues 117 and 139. Done should mean the reported controls and key interaction work in that setup, or their availability and persistence are clearly documented.
