Hi,
Thanks.
Indeed, the rendering of "i" is not yet satisfying.
The "i" is about inspecting which in the GT environment always spawns another inspection session - and at this moment, this maps on a new window. Appearing to the right of the playground, you do "open". I still want this to come, but the thing is that the current behavior is implemented independently of the (gt)playground, and this is why we cannot yet open. But, we will work on this.
About "i" and "e", in GT there is no hardcoded explore. There exists only an inspect which leads you to object specific views. Hence, everywhere in the GT environment, you will see either "i" or the triangle for "open".
Cheers,
Doru
