A few suggestions

1) Is it possible to add holding pattern by clicking on a map's object (vor, fix, etc. or just by making a long tap if there isn't any object at all) and setting desired radial and distance? Right now, if ATC will put you on hold there is just no way you can visualize if you keep yourself within prescribed (safe) limits.

2) Can you add an option to overlay my own set of approach plates (geo-referenced in GlobalMapper software & saved as .sqlitedb/.mbtiles format) over currently selected map? Just like in Garmin Pilot app.

3) Satellite weather overlay also would be a nice addition, although I can't really suggest any source of information, because I don't know how the data is going to be injected into the app. A few good website to check: windy.com, rainviewer.com.

4) It would be great if you can add approximate wind speed & direction derived from a groundspeed via couple turns (or else).

1. Yes

2. You can import them, if it is in Slippy Mercator format (tiles in directories)
Menu / Downloads / Topo map
Menu / Import

3.
I do not find any suitable free data source. If you know about it, please let me know.

4.
Wind speed and direction can be easy derived, when soaring. But when you fly from A to B, it is impossible. If you know how, please let me know.

2. I would like to make an overlay with a 50% transparency (optionable) over currently displayed *.sqlitedb map (I use OFM maps) and launched from a PDF folder of an airport. See video above or picture below.

4. I can do a couple turns in flight without a problem. Is it going to be enough to calculate current wind speed and direction? Can you make an option then to display it in

Concerning 4, a possible way ahead (used in other apps) is to trigger a "measure wind" function on request.
The pilot starts a rate 1 (or even rate 2 or more) turn, trying to keep a stable indicated speed.

The application could display kind of a compas or a simple circle to show the progress of the turn or simply popup a message when completed.
Possible check: if the turn rate varies too much, a warning could be displayed and the data discarded.

FIF should determine the maximum and minimum ground speed and the corresponding heading.
wind speed = 1/2 speed difference
wind origin = (heading.minspeed + heading.maxspeed - 180°) / 2

Of course, a more accurate calculation is possible fitting a sinusoidal speed evolution using the least square method, but the key for the accuracy is the constant indicated speed.

Yes, this is possible. If you are OK with 360 turn, I will implement it.

A rate 2 turn takes just a minute, so yes, it is OK to perform a 360.

Can we also have a "Glide advisor" feature from ForeFlight ? :)

this would be awesome, integrated with terrain data, showing where you cluld reach with your given altitude and best glide ratio of your aircraft.

This would indeed be a nice feature, but not so easy to implement due to the terrain analysis.
I had it in a previous application on WM6.1

Advice: manually input a rather conservative value of the aircraft glide ratio to make provision for vertical currents and wind.
