The tooltip for the certified credstick has how to do that.

You add Custom Data to the credstick with a value equal to the nuyen you want on it. Just call the data Nuyen or Cash or whatever you like.

Suggestion.

Add the following specializations to the Pistols skill: Light Pistols, Heavy Pistols. There are sample characters with at least Heavy Pistols as a specialization.

Knowledge Skill: Paracritters - Knowledge Skill: Skill Name Must be Specified

The Knowledge skill was added after creation. Not that it matters, gives the same error when selecting one made at character creation.

Incorrect Starting Nuyen Dice Roller
 

Background:
The starting nuyen calculator doesn't work properly. It fails to account for bonus values from lifestyle/leftover nuyen.

Steps to Recreate:
1.) Create a new portfolio.
2.) Add a new identity and lifestyle. Select Low Lifestyle.
3.) Hit the roll button for starting nuyen values. Continue for several rolls - note values far below what should be possible (200) and none even hit the average value (975).

Other Thoughts:
Looks like it is rolling based off the lifestyle, without the extra dice from leftover nuyen. That is the calculations are 3d6x50, not (3d6+9)x50. Very minor issue.

You can also do this manually if you like. Hit the "Tags" button, Click to add another tag, then in "Group Id" type "Mode". In "Tag Id" enter the type you'd like:

Single = Single Shot
SemiAuto = Semi-automatic
Burst = Short Burst (I think)
LongBurst = Long Burst
FullAuto = Fully Automatic

I agree though that something with checkboxes or otherwise would be nice.

That is the rating of the sin you are buying that goes with the lifestyle.

? Am I missing a game rule (optional or otherwise) somewhere?

Not sure if this CAN be handled, but essence is increased when you remove cyberware. character can never regain essence due to bioware/cyberware (escept for some fairl rare and radical procedures in Runners Companion? So when yu add or update your 'ware there is an essence "hole" that can be filed with additional 'ware with no essence penalty.

Also AFAIK by RAW you are also supposed to track essence lose from bioware and cyberware separately. Never had a game come up where a char had both though so it might be a corner case.

Size costing isn't being factored in.

Typically a lifestyle has a fake sin tied to it. You have to be paying the bills with an identity of somekind. You might be able to argue with the gm that a low lifestyle or lower could be paid using certifieds every month. You could be leasing the space from the local gang and they don't care who you are as long as you pay. However you would still have problems with comm service, utilities etc... needing a name on the bill. Of course you could pirate those as well. However that brings other problems with it. I would say that a mid lifestyle or higher needs a fake sin attached to it. There is just too much exposure to the legit world to get around.

Now conversely, a fake sin does not need a lifestyle tied to it. My current character has one lifestyle and two fake sins. One sin is tied to the lifestyle but the other is used for more risky things. If it gets comprimised, I toss it and buy a new one. Nothing gets traced back to my lifestyle, so I don't lose that as well.
