These overview tabs are highly customizable, and I encourage you to spend a little time creating your own. Because you can import and export your whole overview set between characters, you only need Or, you can search for "Eve overview packs" to find some pre-made ones. I don't use any of them, though, so I can't recommend a good pack. I put together about two dozen of my own combinations, which I use for specific situations. My standing overview tabs are:
- PvP: Despite the name, my first overview includes everything that could do damage to me or be relevant for PvP, including NPCs, bubbles, and basic warp-outs.
- Reds + Gates: Includes only non-blue, non-fleet member ships and stargates. This tab is for when I'm in a fight or scanning for targets and don't want the extra clutter.
- Fleet: One of the new tabs added since the 5-to-8 expansion, this tab includes only fleet members.
- Loot: Wrecks and cargo containers; incidentally, my cargohold also has a filter for 5 mil+ loot.
- Misc: Jack-of-all-trades overview tab, which I swap out as necessary with my niche presets.
- Planet: The second of the new tabs, the planet tab used to be one of my "misc" profiles.
- Belts: The third of the new tabs, also populated "misc" occasionally.
- Probes+Bubbles: As my last tab, I can shift+tab to this one from my primary tab, "PvP" to quickly check the area for anything that might block my travel, including anchored and dictor bubbles.
But all of that would be highly confusing if not for one fun option: overview tab colors! After all, it's easy to forget which tab you're on, or what the different tabs are for. Eight tabs is a lot for the eye to capture, and it's a psychological fact that the maximum number of elements an average person can keep in their mind at once is 7. Some can manage more, some can manage fewer. Colors help break up the tabs. But, there's no easy way to set up color options.
Rather than reproduce the description of how to add color to your overview tabs, I'd prefer to refer you to the master reference at stackexchange.com. Follow this guide and you can sort your overview in a quick, meaningful way.
This is much easier to keep track of. If you don't like the colors indicated in the guide, you can choose any colors you want. Just reference a color code guide and change the field within the color tag.
Anyways, experiment and find something that works for you. But, with eight overview tabs to use, you shouldn't ever lose a ship - or an opportunity for a kill - because of fumbling for the right preset.
Good luck out there!
