Return Ore sites to Red Signature: Mining in W-Space is one of the most dangerous activities you can do. Back when they were Red Signatures you at least had protection in seeing probes on Dscan. As Green Anomalies that safety is gone and the miner is at the mercy of it's natural predators. Moving these back to Red Signatures would return the degree of safety back to miners, as well as making things interesting for those who hunt them as it used to be. This only needs to be a W-Space change, K Space can stay as it is. As an addition, making the Signature harder to scan down would also be nice.

Drifting Wormhole: Over DT, something is done to the precise location of the WH. As such after DT it is in a slightly different location, anywhere from a few hundred meters up to a dozen kilometres. This means remaking bookmarks for WH's along the entire chain so they're accurate. Having the WH not drift over DT by either doing whatever is causing the shift in location at initial spawn or just not drifting it would be nice.
Additional possibility: Embrace the drift. Have the WH every 15 minutes to two hours randomly drift in a random direction up to 100km. This would shake up WH camps into something a bit more chaotic.

Update BM location: Recreating bookmarks when they're wrong is a bit of an annoyance. Having inside the Right Click menu for the Bookmark the option to either update to current co-ords or update to current selected object's co-ords would be amazing.

Offgrid spawns: Occasionally one of the C4 Data or Relic sites spawns Sleepers off-grid. Sorry I can't remember which one exactly it is. I don't know if this is fixed or I just haven't seen it in a while.

New environment backgrounds: Can we get our space extra pretty as well please :)
Side Note: Can the C1 and C2 backgrounds be made more different. They're pretty close at a glance currently, especially when looking at it as part of a WH effect. A nice pretty green for C1's.

Security Status reset: Currently there's no way to change your security status in W-Space. If you go in negative, stay for a few years and come out you're still negative. It's be nice if gradually over time Concord "forgot" about you. Have the Sec Status slowly degrade towards zero (From both positive and negative) the longer you stay out of K Space. Something like the equivalent of ratting a single frigate for each day. Each day beyond one the strength of the sec status change could get slightly stronger so those who don't hit K-Space in any way for long periods, months for example, would get pretty decent sec status changes.

Epithal and Warp Core Stabilisers: 4 core stabbed Epithals. Needing 5 points of disruption to stop one of these is kind of ridiculous. Especially since the stabs don't do anything negative to the performance of the hauler. A reduction of lows or changes to the warp core stabiliser to make it's negative effects something relevant to non PvP ships would be best.
Noctis and Mobile Tractor Unit: The MTU has pretty much invalidated the existence of the Noctis. Can we get a rebalance on these so they have individual uses. Or better yet, send the MTU out back and burn to to death with a flamethrower.

WH Polarisation: Polarisation timers are directional A>>>B and B>>>A. For newer WH people this is confusing as from the players point of view, the WH is one object and having multiple separate timers is odd. Could these be squashed into the one timer, so A>>>B and B>>>A use the one timer. It should probably be rebalanced into a shorter timer overall as well if this is done.
Additional possibility: Have the polarisation timer modify based on the ship flown. Ideally off of Sensor Strength as this'd give a nice buff to larger ships, who could transit WH's faster. It's also give a nice buff to ECCM.

Hide 0% sigs: Currently under the Discovery Scanner a layer is alerted to a new signature whenever the Discovery Scanner wIndow refreshes itself. This is done automatically by the Scanner to an invisible timer and can also be forced by changing the sort of any of the columns or toggling the anomalies button. Due to the way WH's are spawned this means that people in the arriving system know about an incoming WH before the person who initiated warp to the WH arrives at that WH. There's been talk about a delay on the signature appearing before in a megathread but ideally the fix is simple. any signature at 0% inside W Space does not show up in the Probe Scanner Window. This would revert the system to the old way. The good way.
