Not sure if this is possible, but some sort of solid inspector. Alot of people using the online version could benifit from this, especialy if they are not using solidtools and since extensions for the browser edition looks crazy hard to do, which means no booltools2, then a fair option would be at least some sort of solid inspector
also, maybe an upgrade for just solidtools for like $30 or $40 Just for solid tools.
If this allready exists in the free version, im sorry. i didnt see it, but if it does not, i think its a good idea:)
