You can offline gear by ctrl-left click the green tick.
BTW:
1. Named Invuln Field
2. in fact, named afterburner and shield booster.
3. I think Cap boosters are overrated in small ships - drop it and try a cap battery instead.
Also, click the tick by the afterburner and cap booster, this will show you what you're probably going to do most time (i.e. not afterburner and not cap boosting). If you can make this cap stable, then the rest will fall into place.
1) I don't have named Invulnerability Fields stocked. They cost loads, but I'll aim for one.
2) Even the best named shield booster provides just a ~2% shield strength addition compared with the "regular" on the Harpy with my skills. If I'll stumble on a named one, yes I will take it, but it looks to me paying millions for such a minimal boost is not worth the money at this moment.
Named Afterburners cost a lot too, altough their effectiveness seem to me to be a bit better. Will keep my eyes open for these, altough I don't go bananas for one.
3) There is one (actually two) significant difference between cap booster and cap battery: Capacity and CPU. I simply can't fit a cap battery on the Harpy without dropping out something (like a gun) instead.
The fitting seems to be stable when the Medium slots are not activated, and with everything turned on the capacitor lasts for 43 seconds.
