1) is there an exec command to act/deact blocks of triggers like eff: activate tr#13-26? (somewhere a list of available execs?)
2) how can i guarantee a spawn unit point is free? ---> cannot "eff: delete obj" on an empty tile, but there's random chance of player/opp/gaia/item being there
3) there's "eff: declare victory" but no declare defeat (unit/item/whatever destroyed)
4) is the solid forest/shrub tile gone? sometimes visually better than laying out the mini-tree tiles (and still block siege paths)
5) is there a cond/eff limit per trigger? haven't hit one but on my next idea i might
finally what happens then when i hit send to market? i assume its reviewed before publicly available?
Thx for any help, I'm looking forward to sharing my work
there is eff: deactivate trigger (X) to deactivate a single trigger. You can add several eff with different trigger numbers or you can chain through consecutive triggers. But effecting many triggers at once is not available. Maybe you can suggest one in the suggestions. 
if you mean the spawn point for eff: create obj at X/Y 
What do you mean? If a player wins, the other player loses. So if you want to declare defeat for a player, you can simply declare victory to other player.
i hope terrain forest (that can be cleared by worker) 
No. Atleast
