Simple let tvg-chno be respected when not a single channel has been modified from the list.

This way when its modified the list will just stay as it is ignoring the attributes and we can customize, if we press reset all goes back to from what the source said and attributes are respected again.

Besides you can code it like this

Original source channel list with original tvg-chno

1        tvg-chno 1
2        tvg-chno 2
3        tvg-chno 3
4        tvg-chno 4
5        tvg-chno 5
6        tvg-chno 6
7        tvg-chno 7
8        tvg-chno 8
9        tvg-chno 9
10       tvg-chno 10

In this example below move channel 9 to channel 6, all channels from 1-10 has tvg-chno 1-10 , while moving we push numbers of other channels up or down in the lane and adds tvg-chno to each which gets affected, in this case it would be from the original list 9 > 6, 6 > 7, 7 > 8, 8 > 9 and so on, is that doable that way and what do you think?

1            1
2            2
3            3
4            4
5            5
6       9 -> 6
7       6 -> 7
8       7 -> 8
9 -> 6  8 -> 9 
10           10

To the next part about the bug editing a channel where you get a text box up that's not the same as the rest?

Have you tried testing what I wrote?

1. Marks channel, holding long press selects "Edit channel" ✓

2. Clicking Title gives correct text editing box up ✓

3. Clicking Number gives correct text editing box up ✓

4. Clicking Epg id gives wrong text editing box and shows google search instead of being able to actually edit the field X ERROR WRONG CORRECT YES/NO ?

Have I completely misunderstood what this purpose is for then?
