Add option to keep screen center unchanged when point is tapped

Hello Georg,

what is the most common use case you try to solve with this? It is a little unusual and I currently do not see a serious reason for this. But I'm open to discussing of course :).

When verifying tracks on an offline map, the center moves, making it difficult to work. Using Orux Map.

Hi Menion, I named 3 use cases in initial post and all 3 are same likely. First one in more detail with an example: I'm preparing a trip. I read about something interesting and add a point roughly in the correct location. During the trip, I see I'm coming to that area, so I want to increase the point's location as much as possible. For that, in Locus 3, I want to make use of all Locus features like using multiple maps (sat, vector, hand drawn), changing vector map theme or it's configuration, reading descriptions of several nearby points (e.g. "around 200m north-west is..."),... Using all these feature is currently not possible (and it makes no sense) within "select location > select on map" of the desired point. Instead, I iteratively move the screen center to desired location, doing mentioned actions, and finally open the desired point and set it's location to screen center. This process is not possible in Locus 4 because screen center is moved all the time by the system instead of staying where I moved it.

Thanks, but I'm not perfectly following your example.

- changing maps/themes etc. should not be connected to centering on a selected point

- distance & bearing in the point detail are usually computed from your current location, so the map center does not affect it

Maybe someone other has an easily describable use case that is really complicated because of the current system?

- While changing maps/themes etc. should not be connected to re-positioning a selected point, it in fact is because in "point detail > select location" it's impossible to change map/theme.

- You're right, that's why distance & bearing in the point detail is of no use in mentioned situation, while two finger measurement works between two abitrary positions.

For the frequent use case (1-2 dozen times a day) refining the location of an existing point, using "screen center" was quick & easy and my favorite way in Locus 3 – but it is obviously not your intended workflow for Locus 4. What is your suggested workflow? here a video showing one example instance of the use case. In beautiful Húsafell area I searched a place where we could ford Kaldá because the cliffs mentioned at the beginning turned out to be too massive for hiking down to the track (in this picture, the white dots on the grass are sheep so around 1m high).

Because you discouraged "screen centre", I did have again a closer look at "point detail > select location" but I only no workflow being nearly as quick & easy as "screen centre" in Locus 3:

• My location & Stabilisiertes GPS: Not usable. Desired position is not my current GPS fix location
• Search: Not usable. It can't find what I look for because there is nothing mapped point/way in OSM data
  
• My points:
  I do not yet have a point at correct position – that's the aim of my current action.
  I could create a temporary dummy point at screen center, then open my "real" point, select location, search the dummy point, save, the open the dummy point and delete it – but that's much more work than just tapping "screen center" as in Locus 3
• Select on map: It misses most of the features the main map screen has (switching maps, access to quick settings, switching WMS,...) and that I use to determine desired location
  
• Screen center: Not usable in Locus 4 because it moved screen center away from the identified desired location to the position of selected point.
  
• Coordinates: Not usable. I don't have any I could type in
• Contact: Not usable. Noone is living at desired position
  
• Projection: Would require me to do a two finger measurement that's relatively precise – with my thick fingers, that's always tricky, and it's nearly impossible in the field with wet cold fingers in strong wind – then memorize distance & bearing, and type that values it in again, so more work & error prone than just tapping "screen center" as in Locus 3
• Clipboard: Requires me to change top bar ("information") back & forth between Map or GPS (what I usually want) and coordinates (so that I can copy current screen center to clipboard by long tapping top bar). It is 6 taps more work than just tapping "screen center" as in Locus 3, and it is littering my clipboard replacing desired content.
