Missing base58 WIF chars at unknown place.Example 8/12 not working,BIP38 password limitation,no Stop button,Missing WIF chars limit about finderouter HOT 2 OPEN

Hello and thanks for your feedback.

1. After adding the SearchSpace option, this feature was disabled
   0e66f6e#diff-53ca38a010e48324cc9ccc6dac05df12b1e118054ff23a4565eb570a8b092938R1253-R1254 I'll have to add it as a separate recovery option.
2. If each position needs to go through all 58 characters, there is no need to touch the "Advanced" section at all to manually enter the chars since they are filled automatically. SearchSpace option is for when you want to limit the characters. However, I'll try to add a "copy list" option to ease that process (eg. copy an entered list from position 2, then paste it for position 5).
3. It is in my todo list...
4. It's a limit. The missing chars from end method is an optimization that only works when the checksum is the missing part or the bigger part of what's missing. With 12 missing chars in a compressed WIF, the bigger part that's missing is the key itself and the number of permutations that have to be checked shoots up to over 1.3 billion and cannot be solved within reasonable time. You can see this exponential growth here:

   FinderOuter/Src/FinderOuter/Services/Base58Service.cs

   Lines 104 to 113 in 4cbaaeb

   	// Numbers are approximates, values usually are ±1
   	// Uncompressed ; Compressed
   	// 1-5 -> 1 ; 1
   	// 6 -> 9 ; 1
   	// 7 -> 514 ; 3
   	// 8 -> 29,817 ; 117
   	// 9 -> 1,729,387 ; 6,756
   	// 10 -> 100,304,420 ; 391,815
   	// 11 -> 5,817,656,406 ; 22,725,222 <-- FinderOuter limits the search to 11
   	// 12 -> ; 1,318,062,780

5. That error message sounds like a bug that I have to investigate further.
