My Two Cents

1) Until they reinstate the use of the "goodsaves" in the class document, that's not gonna be possible, and there are so many other things that affect saves that even then, the saves would be off for lots of characters due to class abilities (like the Paladin), feats, and magic items. Don't get me wrong, I'd love this too, but they need to add more functionality to a lot of things before that's possible.
2) Oh, believe me, I know the hassle it would save you. I use HL as well. The problem is that the two do not share a format with the characters, thus the reason you need to export it as a special .hld20pro file, and then import it using a specific plugin that converts .hld20pro files into a .d20_ctr file. A lot of data is lost in the transfer, and characters can only be imported wholesale. This is the most complex idea to implement in your list, and would take either d20Pro and/or Hero Lab changing and integrating their entire file structure. Not necessarily impossible, but not something we'll see any time soon, as much as I'd love it.
3) Since caster level checks use class level rather than BAB, and classes don't stack for this purpose, I agree, a caster level check addition would be great.
4) This would take expanding what feats are capable of in the program, which needs to be done anyway.
5) Eh, this would be nice, but since I rarely use the draw tool for such, not so important for me.
6) This would be cool, but since system messages, ooc messages, and quite a few other messages are already in different colors, I could see this getting kinda confusing.
7) I requested this before myself. The ability to have conditions and not have to remember to apply the effects beyond putting the condition on the character would be uber awesome.
8) A thousand times yes! A THOUSAND times yes!
9) Much agreement on this one as well. Honestly, one of the best avatars I've ever seen.
10) This can't be said enough.

 

Effects which target ability scores, such as ability damage to CON when applied as an effect onto the character automatically adjust the HPs and Fort save.

 

Effects can target ability score and hit points and saves are adjusted due to their modification. though changing of the stats on the character sheet will not impact the ability saves or hit points.

Thank you guys for the input. On my table is an effects library, which will give you the ability to place the sicken effect on a creature and it will get the status icon and modifiers quickly and easily.
